Abstract

An object of the present invention is to provide a substrate attached with a decorative material in which a problem such as the disconnection of a conductive layer is solved, and a manufacturing method thereof, a touch panel, and an information display device. According to the present invention, there is provided a substrate attached with a decorative material, including: a substrate; a white colored layer; a light shielding layer; and a conductive layer, in this order, in which the substrate attached with a decorative material includes a light transmitting region transmitting light in a thickness direction, a decorative material configured of the white colored layer and the light shielding layer is laminated on the substrate to surround the light transmitting region and includes a tilt portion which is formed such that a thickness of the decorative material becomes thin towards the inside of the light transmitting region on an inner edge of the decorative material, and a tilt angle between a surface of the tilt portion and a surface of the substrate is 10 degrees to 60 degrees.

First claim

What is claimed is:

1 . A substrate attached with a decorative material, comprising:
a substrate; a white colored layer; a light shielding layer; and a conductive layer, in this order, wherein the substrate attached with a decorative material includes a light transmitting region transmitting light in a thickness direction, a decorative material configured of the white colored layer and the light shielding layer is laminated on the substrate to surround the light transmitting region and includes a tilt portion which is formed such that a thickness of the decorative material becomes thin towards the inside of the light transmitting region on an inner edge of the decorative material, and a tilt angle between a surface of the tilt portion and a surface of the substrate is 10 degrees to 60 degrees.

2 . The substrate attached with a decorative material according to claim 1 ,
wherein the light shielding layer is a thermally crosslinking resin.

3 . The substrate attached with a decorative material according to claim 2 ,
wherein the thermally crosslinking resin is a resin having a siloxane bond in a main chain.

4 . The substrate attached with a decorative material according to claim 3 ,
wherein the resin having a siloxane bond in a main chain is a methyl silicone resin.

5 . The substrate attached with a decorative material according to claim 1 ,
wherein the white colored layer contains a resin having a siloxane bond in a main chain.

6 . The substrate attached with a decorative material according to claim 2 ,
wherein the white colored layer contains a resin having a siloxane bond in a main chain.

7 . The substrate attached with a decorative material according to claim 3 ,
wherein the white colored layer contains a resin having a siloxane bond in a main chain.

8 . The substrate attached with a decorative material according to claim 5 ,
wherein the resin having a siloxane bond in a main chain is a methyl silicone resin.

9 . The substrate attached with a decorative material according to claim 6 ,
wherein the resin having a siloxane bond in a main chain is a methyl silicone resin.

10 . The substrate attached with a decorative material according to claim 7 ,
wherein the resin having a siloxane bond in a main chain is a methyl silicone resin.

11 . The substrate attached with a decorative material according to claim 1 ,
wherein a difference between a width of the white colored layer on the substrate side and a width of the light shielding layer is less than or equal to 200 μm.

12 . The substrate attached with a decorative material according to claim 2 ,
wherein a difference between a width of the white colored layer on the substrate side and a width of the light shielding layer is less than or equal to 200 μm.

13 . The substrate attached with a decorative material according to claim 3 ,
wherein a difference between a width of the white colored layer on the substrate side and a width of the light shielding layer is less than or equal to 200 μm.

14 . The substrate attached with a decorative material according to claim 5 ,
wherein a difference between a width of the white colored layer on the substrate side and a width of the light shielding layer is less than or equal to 200 μm.

15 . The substrate attached with a decorative material according to claim 8 ,
wherein a difference between a width of the white colored layer on the substrate side and a width of the light shielding layer is less than or equal to 200 μm.

16 . A manufacturing method of the substrate attached with a decorative material according to claim 1 , comprising:
a step of transferring a light shielding layer and a white colored layer onto a substrate from a film transfer material including at least a temporary support, the light shielding layer, and the white colored layer in this order, and then, removing the temporary support; or a step of transferring a white colored layer onto a substrate from a film transfer material including a temporary support and the white colored layer, and then, removing the temporary support, and transferring a light shielding layer onto the white colored layer from a film transfer material including at least a temporary support and the light shielding layer, and then, removing the temporary support.

17 . The manufacturing method of the substrate attached with a decorative material according to claim 16 ,
wherein the tilt portion is formed by contracting the light shielding layer.

18 . The manufacturing method of the substrate attached with a decorative material according to claim 17 ,
wherein the tilt portion is formed by being heated at 50° C. to 300° C.

19 . A touch panel, comprising:
the substrate attached with a decorative material according to claim 1 .

20 . An information display device, comprising:
the touch panel according to claim 19 .
