    摘要: A coating composition comprising (1) a partial condensate obtained by subjecting a silane compound of RmSiX4−m to hydrolysis and partial condensation with a sufficient amount of water to meet a molar ratio: 1.2≦H2O/Si—X≦10, (2) a vinyl polymer having UV absorbing groups and hydrophilic groups which is dissolvable or dispersible in a water-containing hydrophilic solvent, and (3) a hydrophilic organic solvent can form a hard protective coat having improved weather resistance.
