Imd/imr transfer pattern method

An IMD (in-mold decoration)/IMR (in-mold roller or in-mold release) transfer pattern method comprising the steps of:

• (1) preparing an in-mold transfer-pattern film comprising a thin film substrate, a adhesive layer, a release layer between said thin film substrate and said adhesive layer, a hard coat layer between said release layer and said adhesive layer, and a pattern layer provided between said hard coat layer and said adhesive layer;
• (2) trimming the in-mold transfer-pattern film to a predetermined size;
• (3) processing the trimmed in-mold transfer-pattern film from (2) into a predetermined three-dimensional shape;
• (4) inserting the trimmed and shaped three-dimensional in-mold transfer-pattern film from (3) in a cavity of an injection-molding mold and filling a molten plastic material into said injection-molding mold and injection-molding the filled molten plastic material on the three-dimensional in-mold transfer-pattern film in the cavity of the injection-molding mold to form a molded product;
• and
• (5) removing the molded product from the injection-molding mold after the injection-molding mold has been cooled down and then removing the thin film substrate and the release layer of the in-mold transfer-pattern film from the molded product.
