Abstract

A decorative member as a three-dimensional molded article is formed in a curved sheet shape. In the decorative member, a plurality of cylindrical lenses is arrayed in parallel on one surface. In cylindrical lenses in a molding portion and cylindrical lenses in a molding portion, the orientations of the lenses are different from each other. In addition, in the cylindrical lenses in the molding portion and the cylindrical lenses in the molding portion, the shapes of cross sections of these cylindrical lenses in the array direction are different from each other.

First claim

What is claimed is:

1 . A molding material comprising:
a thermosetting compound that cures by heating; and a transparent polymer which is obtained by curing a thermosetting compound, wherein the molding material is formed in a film shape, and a plurality of cylindrical lenses is arrayed in parallel on one surface of the molding material.

2 . The molding material according to claim 1 , further comprising:
a convex lens layer forming a convex lens surface of the cylindrical lens; and a transparent layer forming a flat lens surface of the cylindrical lens.

3 . The molding material according to claim 1 , further comprising:
an image-forming portion in which an image is formed using paint on the flat lens surface of the cylindrical lens.

4 . A three-dimensional molded article comprising:
a plurality of cylindrical lenses arrayed in parallel, wherein the three-dimensional molded article is formed in a curved sheet shape, the plurality of cylindrical lenses includes a first cylindrical lens and a second cylindrical lens in which orientations of the lenses are different from each other, and the first cylindrical lens and the second cylindrical lens have mutually different cross-sectional shapes in an array direction.

5 . The three-dimensional molded article according to claim 4 , further comprising:
a transparent polymer obtained by curing a thermosetting compound.

6 . The three-dimensional molded article according to claim 4 , further comprising:
a convex lens layer forming convex lens surfaces of the first cylindrical lens and the second cylindrical lens; and a transparent layer forming flat lens surfaces of the first cylindrical lens and the second cylindrical lens.

7 . The three-dimensional molded article according to claim 4 , further comprising:
an image-forming portion formed using paint on the flat lens surfaces of the plurality of cylindrical lenses.

8 . A method for producing a molding material comprising:
a coating step of applying a coating fluid including a thermosetting compound that cures by heating to a support, thereby forming a coated film; and a lens-forming step of pressing the coated film using a shape-imparting member having a plurality of semicircular column-shaped concave portions formed on a surface thereof so as to form a plurality of cylindrical lenses, heating the coated film so as to be cured in a state in which the thermosetting compound remains, and producing a molding material including the thermosetting compound and a polymer which is obtained by curing the thermosetting compound.

9 . The method for producing a molding material according to claim 8 ,
wherein the shape-imparting member is a shape-imparting roller having the concave portion formed in a circumferential surface thereof.

10 . The method for producing a molding material according to claim 8 , further comprising:
a shaping step of carrying out a shaping treatment on the molding material under heating, to shape the molding material into a three-dimensional form.

11 . The method for producing a molding material according to claim 10 ,
wherein the shape-imparting member is a shape-imparting roller having the concave portions formed in a circumferential surface thereof.
