UNDERCOATING AGENT FOR PLASTIC ATTACHMENT INORGANIC THIN LAYER, PLASTIC ATTACHMENT INORGANIC THIN LAYER AND DECORATION FILM FOR IN-MOLD MOLDING OR INSERT MOLDING

摘要

PURPOSE: An undercoating agent for inorganic thin film-adhesive plastics is provided to ensure excellent adhesion to a metal thin film layer and to prevent the generation of a blooming phenomenon or big cracks in a high temperature environment. CONSTITUTION: An undercoating agent for inorganic thin film-adhesive plastics comprises a copolymer(A) and polyisocyanates(B) having at least 3 isocyanate groups in molecule. The copolymer(A) is formed by reacting a monomer(a1) represented by chemical formula (1): CH2=C(R^1)-[-(C=O)-O-]_m-X and a monomer(a2) represented by chemical formula (2): CH2=C(R^2)-[-(C=O)-Y^1-]_n-Y^2. The concentration(mol/g) of a hydroxyl group is 0.001~0.005.
