ABSTRACT:
A method for manufacturing the half body portions of a magnetic tape cassette or the like having an image transfer layer on its outer surface. An image transfer film is placed in a molding cavity, which film includes a base layer, a matting layer, and an image transfer layer. The function of the matting layer is to roughen the surface of the image transfer layer, while allowing easy subsequent peeling therefrom. A molten plastic is injected into the molding cavity against the image transfer layer. After the resulting product solidifies, the product is removed from the molding cavity, and the base layer and matting layer are peeled from the product, leaving the image transfer layer on an outside surface of the product.
