Patent ID: 7504450

Claim:
A composition for absorbing UV light, consisting essentially of a) 0.01% to 20% by weight of inorganic particulates selected from the group consisting of zinc oxide, titanium dioxide, alumina, calcium sulfate, barium sulfate, calcium carbonate, and a mixture thereof, b) 99.99% to 70% by weight of a binder consisting of a resin selected from the group consisting of (i) a resin formed from a monomer of Formula (I) with styrene and (ii) a resin formed from the monomer of Formula (I) with a tertiary carboxylic ester, wherein R 1 is hydrogen or methyl; and R 2 is hydrogen, a C 6 -C 18 aromatic group, a C 1 -C 18 aliphatic group, or a hydroxyalkyl group of formula C n H 2n OH wherein n=2˜10, and c) 0 to 10% by weight of curing means for crosslinking the binder through chemical bonding of molecules thereof, wherein the particle size of said inorganic particulates ranges from 1 to 100 nanometers.
