ABSTRACT:
Moldings possessing a front or rear layer of different properties and capable of backlighting, and a method for the manufacture thereof by proceeding so that after printing, by means of the screen printing method, in such a manner that the thickness of the ink layer, applied as a simple layer on a 0.1 mm-2.0 mm thick synthetic resin sheet, will be 4.mu. or more (preferably 5.mu. or more), or that the thickness of the ink film layer, applied in two or more layers, will be 8.mu. or more (preferably 10.mu. or more), or, alternatively, that the thickness of the ink film applied as a simple layer will be 4.mu. or more (preferably 5.mu. or more) and the thickness of the ink layer applied in two or more layers will be 8.mu. or more (preferably 10.mu. or more), and after processing in a form so that the synthetic resin sheet thus printed can be charged inside the molding die, the die is charged so that said synthetic resin sheet is adjacent to the inner surface of the die, whereupon the molten resin for the forming of the molding is injection-molded after said die has been closed.
