Patent ID: 7052770

Claim:
A hardcoat composition comprising (A) a hydrolytic condensate having a weight average molecular weight of less than 2,000 obtained by hydrolytic condensation of at least one hydrolyzable silicon compound of the general formula (1): R 1 a SiX (4-a) (1) wherein R 1 is an organic group having 1 to 18 carbon atoms, X is a hydrolyzable group, and “a” is an integer of 0 to 2, with the proviso that a compound of only a=0 and a compound of only a=2 are excluded, with at least 1 mole of water per mole of the hydrolyzable group X, (B) a metal oxide, (C) a siloxane resin represented by the average compositional formula (2): R 2 b Si(OR 3 ) c (OH) d O (4-b-c-d)/2 (2) wherein R 2 is independently an organic group having 1 to 18 carbon atoms, R 3 is independently an organic group having 1 to 4 carbon atoms, b, c and d are numbers satisfying 0.8≦b≦1.5, 0≦c≦0.3, 0.01≦d≦0.5, and 0.801≦b+c+d<2, and having a weight average molecular weight of at least 2,000, which is solid at a temperature of not higher than 40° C., and (D) a curing catalyst.
