REACTIVE ULTRAVIOLET ABSORBER AND COATING LIQUID FOR FORMING ULTRAVIOLET SHIELDING FILM, ULTRAVIOLET SHIELDING FILM, AND SUBSTRATE FORMED OF ULTRAVIOLET SHIELDING FILM AND HAVING ULTRAVIOLET SHIELDING FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a new reactive ultraviolet absorber with less bleed-out and curable at the ambient temperature, and a coating liquid for forming a curable ultraviolet shielding film containing the same; an ultraviolet shielding film excellent in adhesion with less aging which is obtained by curing the coating liquid; and a substrate formed of the ultraviolet shielding film and having an ultraviolet shielding function.

SOLUTION: This reactive ultraviolet absorber includes a mixture of a benzophenone derivative having hydroxy and alkoxysilyl, and a benzophenone derivative having silyloxy and alkoxysilyl.
