Kind Code:
A1
Abstract:
[Problem] To provide: a sheet that allows batch formation of a pattern layer on a curved surface, such that the pattern layer is free of distortion, or has very little distortion, caused by curved surface irradiation; a method for manufacturing an article with a pattern layer by using such sheet; and an article with a pattern layer having a pattern layer formed on a curved surface. [Solution] This sheet (1) includes: a first base material (2); a photocurable layer (3) in an uncured state, which is provided on an upper surface (21) of the first base material 2 and includes a photocurable resin (32); and a second base material (4) which is light transmissive and provided in contact with the surface of the photocurable layer (3) on the side opposite from the first base material (2). When the photocurable layer (3) is irradiated with light of a prescribed pattern via the second base material (4), the photocurable layer (3) is cured, and the second base material (4) is peeled off from the photocurable layer (3), an exposed part (3b) of the photocurable layer (3) is held on the first base material (2), and an unexposed part (3a) of the photocurable layer (3) is held on the second base material (4).
