Abstract
Abstract A coated material obtained by applying a coat containing a metallic powder and/or a coloring pigment to a substrate and further applying a topcoat clear coating thereon, wherein said topcoat clear coating is a heat-hardening coat which contains a composition comprising a hydroxyl group-containing resin, a hydrolyzable silyl group-containing polymer and a hardening catalyst as the main component. This coated material is excellent in, for example, appearance, acid resistance, staining resistance, adhesiveness and hardness.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
A coated material obtained by applying a coat containing a metallic powder and/or a coloring pigment to a substrate and further applying a topcoat clear coating thereon, wherein said topcoat clear coating is a siloxy or siloxane crosslinking type thermocurable coating which comprises (A) a hydroxyl group-containing acrylic resin; (B) an alkoxysilyl group-containing copolymer represented by formula: where R¹ represents a C₁₋₁₀ alkyl group; R² represents a monovalent hydrocarbon group selected from the group consisting of hydrogen atom, alkyl group, aryl group, and aralkyl group; and a represents 0 or integer of 1 or 2; and (C) curing catalyst.
Claim 2
Dependent Claim
99 words
A coated material obtained by applying a coat containing a metallic powder and/or a coloring pigment to a substrate and further applying a topcoat clear coating thereon, wherein said topcoat clear coating is a siloxy or siloxane crosslinking type thermocurable coating which comprises (A) a hydroxyl group-containing acrylic resin; (B) an alkoxysilyl group-containing copolymer represented by formula: where R¹ represents a C₁₋₁₀ alkyl group; R² represents a monovalent hydrocarbon group selected from the group consisting of hydrogen atom, alkyl group, aryl group, and aralkyl group; and a represents 0 or integer of 1 or 2; and (C) curing catalyst.

Dependent Claim
110 words
A coated material obtained by applying a coat containing a metallic powder and/or a coloring pigment to a substrate and further applying a topcoat clear coating thereon, wherein said topcoat clear coating is a siloxy or siloxane crosslinking type thermocurable coating which comprises (A) a hydroxyl group-containing acrylic resin; (B) an alkoxysilyl group-containing copolymer represented by formula: where R¹ represents a C₁₋₁₀ alkyl group; R² and R³ each, which may be the same or different, represents a monovalent hydrocarbon group selected from the group consisting of hydrogen atom, alkyl group, aryl group, and aralkyl group; and a represents 0 or integer of 1 or 2; and (C) a curing catalyst.
Claim 4
Dependent Claim
110 words
A coated material obtained by applying a coat containing a metallic powder and/or a coloring pigment to a substrate and further applying a topcoat clear coating thereon, wherein said topcoat clear coating is a siloxy or siloxane crosslinking type thermocurable coating which comprises (A) a hydroxyl group-containing acrylic resin; (B) an alkoxysilyl group-containing copolymer represented by formula: where R¹ represents a C₁₋₁₀ alkyl group; R² and R³ each, which may be the same or different, represents a monovalent hydrocarbon group selected from the group consisting of hydrogen atom, alkyl group, aryl group, and aralkyl group; and a represents 0 or integer of 1 or 2; and (C) a curing catalyst.
