ULTRAVIOLET ABSORBENT AND PACKAGING MATERIAL CONTAINING THIS ULTRAVIOLET ABSORBENT

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet absorbent and a transparent or translucent packaging material containing this ultraviolet absorbent. SOLUTION: This ultraviolet absorbent contains an ultrafine metal oxide particle and a benzotriazole organic compound. The compounding weight ratio of the ultrafine metal oxide particle to the benzotriazole organic compound is 0.1/1-100/1. This ultraviolet absorbent has an excellent ultraviolet absorbing capacity. Packaging materials, such as films and bags, that are molded with a resin composition obtained by adding this ultraviolet absorbent to a synthetic resin are not only excellent in ultraviolet shielding ability but also in transparency.
