Abstract:
A coated article comprising a substrate, an undercoat and an overcoat sequentially applied onto the substrate,said undercoat being made of an undercoat composition comprising a compound having a hydrolyzable group-bearing silyl group represented by SiX3âˆ’a wherein X is a hydrolyzable group and â€œaâ€  is equal to 0, 1 or 2, or a partial hydrolyzate thereof or both, said overcoat being based on a silicone resin-containing emulsion composition comprising a silicone resin-containing emulsion, said silicone resin-containing emulsion resulting from emulsion polymerization of a mixed solution containing (A-1) 100 parts by weight of a silanol group-bearing silicone resin comprising 30 to 100 mol % of structural units (T units) represented by the formula: R1â€”SiZ3, and based on the entire T units, 30 to 80 mol % of structural units (T-2 units) containing only one silanol group represented by the general formula: R1â€”Si(OH)Zâ€²2, wherein R1 is a substituted or unsubstituted monovalent hydrocarbon group, Z is a hydroxyl group, hydrolyzable group or siloxane residue, at least one of the Z groups being a siloxane residue, and Zâ€² is a siloxane residue, said silicone resin having a number average molecular weight of at least 500, and (A-2) 10 to 1,000 parts by weight of a radical-polymerizable vinyl monomer.
