Abstract:
An anti-contamination coating composition comprising a tetraalkoxysilane condensate (C1) which is a tetraalkoxysilane condensate having an average condensation degree of 4 to 20 and which has an alkyl group having 1 to 2 carbon atoms and an alkyl group having 3 to 10 carbon atoms, the alkyl group having 3 to 10 carbon atoms being contained in the amount of 5 to 50% by equivalent based on all alkyl groups in the condensate, said tetraalkoxysilane condensate being present in the amount of 1 to 30 parts by weight in term of SiO2 relative to 100 parts by weight of the solid content of an acrylic copolymer resin (AC) which contains an acrylate and/or a methacrylate monomer and has a glass transition temperature of 0 to 100Â° C.
