Patent ID: 7867573

Claim:
A method of forming a coating on a plastic sheet surface for vehicle interior equipment, comprising the steps of: coating the plastic sheet with a primary composition, the primary composition comprising chlorinated aqueous olefin resin; baking the resulting plastic sheet; coating the baked sheet with a secondary composition, the secondary composition comprising aliphatic urethane; and baking the resulting plastic sheet, wherein the primary composition comprises 30-65 weight % of chlorinated aqueous olefin resin, 2-10 weight % of polyurethane resin, 1-5 weight % of aqueous silicon resin, 0.5-2.0 weight % of aqueous stabilizing agent and 30-60 weight % of distilled water; and the secondary composition comprises 40-60 weight % of aliphatic urethane, 0.1-5.0 weight % of silicon polyol for reforming aliphatic urethane, 3-5 weight % of N-methyl-2-pyrolidone, 0.1-1.0 weight % of neutralizing agent and 30-50 weight % of distilled water.
