摘要: A method is disclosed for improving the UV radiation absorption of a composition containing a UV radiation absorbing agent by adding from about 0.1 weight percent to about 50 weight percent of latex particles, based on total weight nonvolatiles. The latex particles contain a void and have a particle size of from about 100 nm to about 380 nm.
