Interior material including light-blocking layer capable of light emission through various logo patterns and method of manufacturing the same

A method of manufacturing an interior material, comprising the steps of:

• (1-1) joining a lower surface of a material layer and a hot-melt layer together;
• (1-2) attaching a support tape for supporting an island to an upper surface of the material layer;
• (1-3) forming a first lighting groove, through which light passes, by laser-etching a predetermined portion of the hot-melt layer and the material layer;
• (2-1) forming a light-blocking layer on an upper surface of a transparent film through printing or painting;
• (2-2) attaching a binder to a lower surface of the transparent film;
• (2-3) forming a second lighting groove, through which light passes, by laser-etching a predetermined portion of the light-blocking layer;
• (3-1) combining a module resulting from step (1-3) with a module resulting from step (2-3);
• (3-2) replacing the support tape on the material layer with a fresh support tape;
• and
• (3-3) obtaining an interior material by bonding a product from step (3-2) to a base material or an article to be processed, which has a base layer, to obtain a molding material, and then subjecting the molding material to an injection molding process, wherein the injection molding process is performed at high temperature such that the transparent film is melted and stretched to fill the first and second lighting grooves.
