Abstract

A shaped article successfully decorated as desired and a manufacturing method for the shaped article are provided. The shaped article is manufactured by multilayer lamination technique, in which a colored layer, a first transparent layer, and a light reflective layer are formed in this order from an outer-layer side toward an inner side of the shaped article.

First claim

1 . A shaped article, comprising:
a light reflective layer, being formed from an ink having light reflectiveness; a decorative layer; and a first transparent layer, being formed from a transparent ink, wherein the decorative layer, the first transparent layer, and the light reflective layer are formed in this order from an outer-layer side toward an inner side of the shaped article.

2 . The shaped article according to claim 1 , wherein
the light reflective layer is formed from an ink containing a white pigment.

3 . The shaped article according to claim 1 , further comprising:
a second transparent layer, being formed from a transparent ink and formed on the outer-layer side of the decorative layer.

4 . The shaped article according to claim 1 , wherein
the decorative layer has an ink density thereof filled by a transparent supplementary ink in a part of the decorative layer in which a decorative ink alone is insufficient to meet a predetermined ink density.

5 . The shaped article according to claim 1 , wherein
the shaped article includes a plurality of layers stacked on one another, and at least two of the plurality of layers each include a part of the decorative layer, a part of the first transparent layer, and a part of the light reflective layer that are formed in this order from an end side toward a center side of each one of the layers.

6 . The shaped article according to claim 5 , further comprising:
a second transparent layer, being formed from a transparent ink and formed on the outer-layer side of the decorative layer, wherein the at least two of the plurality of layers each include a part of the decorative layer between a part of the first transparent layer and a part of the second transparent layer.

7 . The shaped article according to claim 6 , wherein
a region is provided in which the layers are stacked on one another, the layers each including a part of the decorative layer between a part of the first transparent layer and a part of the second transparent layer, wherein in a portion of the region with no overlap between a part of the decorative layer in one of the layers and a part of the decorative layer in another one of the layers on or below the one of the layers, there is an overlap between a part of the decorative layer in one of the layers and a part of the first transparent layer or a part of the second transparent layer in another one of the layers on or below the one of the layers.

8 . A manufacturing method for a shaped article, the shaped article comprising: a decorative layer;
a first transparent layer; and a light reflective layer, being formed from an ink having light reflectiveness, the decorative layer, the first transparent layer, and the light reflective layer being formed in this order from an outer-layer side toward an inner side of the shaped article, wherein the manufacturing method for the shaped article employs multilayer lamination technique to form layers and comprises a layer forming process, and the layer forming process including: forming a part of the decorative layer, a part of the first transparent layer, and a part of the light reflective layer in this order from an end side toward a center side of each one of the layers.

9 . The manufacturing method for a shaped article according to claim 8 , wherein the layer forming process comprises:
forming a second transparent layer using a transparent ink on the outer-layer side of the decorative layer by forming a part of the second transparent layer at a position nearer to the end side than a part of the decorative layer.

10 . The manufacturing method for a shaped article according to claim 9 , wherein the layer forming process includes steps of:
forming a part of the decorative layer; forming a part of the first transparent layer using a transparent ink; forming a part of the light reflective layer using an ink having light reflectiveness; and forming a part of the second transparent layer using a transparent ink, wherein the manufacturing method for the shaped article comprises:
performing the step of forming a part of the decorative layer, which is subsequent to the step of forming a part of the first transparent layer and the step of forming a part of the second transparent layer, to form a part of the decorative layer between a part of the first transparent layer and a part of the second transparent layer.

11 . The manufacturing method for a shaped article according to claim 9 , further comprising:
providing, in a portion of a region with no overlap between a part of the decorative layer in one of the layers and a part of the decorative layer in another one of the layers on or below the one of the layers, an overlap between a part of the decorative layer in one of the layers and a part of the first transparent layer or a part of the second transparent layer in another one of the layers on or below the one of the layers.

12 . The manufacturing method for a shaped article according to claim 8 , wherein the step of forming a part of the decorative layer comprises:
forming a part of the decorative layer by filling an ink density of the decorative layer using a transparent supplementary ink in a part of the decorative layer in which decorative inks alone are insufficient to meet a predetermined ink density.

13 . A shaped article formed by multilayer lamination technique, comprising:
a decorative layer, wherein the decorative layer has an ink density thereof filled by a supplementary ink in a part of the decorative layer in which a decorative ink alone is insufficient to meet a predetermined ink density.

14 . The shaped article according to claim 13 , wherein
the supplementary ink includes a transparent ink.

15 - 21 . (canceled)

22 . The shaped article according to claim 2 , wherein
the shaped article includes a plurality of layers stacked on one another, and at least two of the plurality of layers each include a part of the decorative layer, a part of the first transparent layer, and a part of the light reflective layer that are formed in this order from an end side toward a center side of each one of the layers.

23 . The shaped article according to claim 3 , wherein
the shaped article includes a plurality of layers stacked on one another, and at least two of the plurality of layers each include a part of the decorative layer, a part of the first transparent layer, and a part of the light reflective layer that are formed in this order from an end side toward a center side of each one of the layers.

24 . The shaped article according to claim 4 , wherein
the shaped article includes a plurality of layers stacked on one another, and at least two of the plurality of layers each include a part of the decorative layer, a part of the first transparent layer, and a part of the light reflective layer that are formed in this order from an end side toward a center side of each one of the layers.
