Patent ID: RE38850

Claim:
A functional coated product having a first coating layer formed of a cured coating of an acryl-modified silicone resin coating material comprising the following components (A), (B), (C) and (D) on a surface of a substrate, and a second coating layer formed of a cured coating of a functional coating material comprising the following components (E) and (F), over the first coating layer; Component (A): a silica-dispersed organosilane oligomer solution obtained by partially hydrolyzing a hydrolyzable organosilane represented by the general formula R 1m SiX 4-m (I) wherein R 1 indicates a monovalent hydrocarbon group having 1 to 8 carbon atoms, which may be the same or different, m indicates an integer of 0 to 3, and X indicates a hydrolyzable group in colloidal silica dispersed in an organic solvent, water or a mixed solvent of them, under the condition that 0.001 to 0.5 mol of water is used based on 1 mol equivalent of the above-mentioned hydrolyzable group (X); Component (B): a polyorganosiloxane represented by the average compositional formula R 2 a Si(OH) b O (4-a-b)/2 (II) wherein R 2 indicates a monovalent hydrocarbon group having 1 to 8 carbon atoms, which may be the same or different, a and b separately satisfy the following condition: 0.2≦a≦2, 0.0001≦b≦3, a+b<4, which contains a silanol group in the molecule structure and has an average molecular weight (in terms of polystyrene) of 700 to 20,000; Component (C): a curing catalyst; Component (D): an acrylic resin of copolymer of first (meth)acrylate represented by the general formula (III) CH 2 ═CR 3 (COOR 4 ) (III) in which R 3 is a hydrogen atom or a methyl group, and R 4 is a hydrocarbon group having 1 to 9 carbon atoms, the second (meth)acrylate of the general formula (III) in which R 3 is a hydrogen atom or a methyl group, and R 4 is at least one group selected from the group consisting of an epoxy group, a glycidyl group, and a hydrocarbon group containing at least either of the above, and the third (meth)acrylate of the general formula (III) in which R 3 is a hydrogen atom or a methyl group, and R 4 is a hydrocarbon group containing an alkoxy silyl group or a halogenated silyl group, and said acrylic resin having an average molecular weight (in terms of polystyrene) of 1,000 to 50,000; Component (E): an organosiloxane comprising a hydrolyzed polycondensate of; 5 to 30,000 parts by weight of a silica compound represented by the general formula: Si(OR 5 ) 4 and/or colloidal silica, 100 parts by weight of a silica compound represented by the general formula: R 6 Si(OR 5 ) 3 and 0 to 60 parts by weight of a silica compound represented by the general formula: R 6 Si(OR 5 ) 2 wherein R 5 and R 6 indicate a monovalent hydrocarbon group and said weight-average molecular weight being adjusted to 800 or more in terms of polystyrene; and Component (F): a photocatalyst.
