Abstract

PURPOSE:To prevent deformation by forming in one body with a metallic reflection layer and a carrying backing material, or the backing material and a laminated plastic plate, and a rigid plastic film having >=1 layer and, at the same time, curving the metallic reflection layer after transferring a desired un even pattern. CONSTITUTION:A metallic reflection layer 2 having a glossy surface or a reflection layer having its glossy surface protected with a plastic thin layer 4 and a backing material 3 (obtained by laminating plastic 3C on a mere backing material 3A with an adhesive layer 3B between), or the backing material 3 and a lamination plate 5 obtained by laminating plastic films 51-5n are united. Simultaneously with of after said uniting operation, a desired finely-uneven pattern is transferred to the reflection layer 2 or the protection film 1 and reflection layer 2 by pressing a total die. Then, the surface is curved by a vacuum heat forming method. In this case, >=1 layer of the backing material 3 or lamination plate 5 uses a rigid plastic film which never creeps even after the curving treatment, thus obtaining a clear vision screen curved to 2,000- 5,000R.
