LIGHT RESISTANCE IMPROVER FOR SYNTHETIC RESIN AND SYNTHETIC RESIN PRODUCT, AND METHOD FOR IMPROVING LIGHT RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a light resistance improver improving the light resistance of a urethane resin and a nylon resin, and products produced therefrom compared to that by nickel p-toluenesulfonate, and not or hardly affecting the coloring of a final product, and to provide a method for improving the light resistance.;SOLUTION: The light resistance is improved by adding at least one kind of nickel mesitylenesulfonate, nickel m-xylene-4-sulfonate and nickel polystyrenesulfonate to the urethane resin, the urethane resin composition or the urethane resin product, or adding at least one of the nickel mesitylenesulfonate and the nickel m-xylene-4-sulfonate to the nylon resin, the nylon resin composition or the nylon resin product.;COPYRIGHT: (C)2011,JPO&INPIT
