  • Patent number: 8420061
    Abstract: Disclosed is an ultraviolet absorber water-dispersed composition, comprising the following components (A) and (B); (A) a benzotriazole-type ultraviolet absorber represented by general formula (1) below wherein R1 and R2 denote alkyl groups having a carbon number from 1 to 18, may be identical or different, and may be substituted by one or two or more groups selected from the group consisting of alkyl groups having a carbon number from 1 to 4, and cycloalkyl groups and aryl groups both having a carbon number from 5 to 12; and (B) polyglycerol monoalkyl ester with a mean degree of polymerization of glycerol of 5 or more. The water-dispersed composition is capable of stably maintaining the dispersed state of benzotriazole-type ultraviolet absorbers even in the presence of salt.
