Hardcoat compositions and hardcoated articles

摘要

A hardcoat composition comprising (A) a hydrolytic condensate of a hydrolyzable silicon compound of formula: R¹_aSiX_(4-a) with at least 1 mole of water per mole of hydrolyzable group X, (B) a metal oxide, (C) a siloxane resin of formula: R²_bSi(OR³)_c(OH)_dO_(4-b-c-d)/2 and having a Mw of at least 2,000, which is solid at a temperature of not higher than 40° C., and (D) a curing catalyst forms a hardcoat film having satisfactory hardness, transparency and adhesion as well as improved weather resistance and presenting a surface that is repellent to marker ink.
