摘要： A coating resin that is thermoplastic, exhibits good appearance, solvent resistance and adherence and is excellent in abrasion resistance; and a coting liquid or coating film thereof. In particular, a (meth)acrylic copolymer resin (A) produced by radical polymerization of 4 to 50 mass % of (meth)acrylic acid (a-1), 0.5 to 17 mass % of (meth)acrylamide (a-2), and 35 to 95.5 mass % of a compound having reactive unsaturated bond other than the compounds (a-1) and (a-2). With respect to the coating film produced therefrom, both the glass transition temperature Tg1 measured by means of a rigid-body pendulum type viscoelasticity measuring instrument and the glass transition temperature Tg2 measured by means of a differential scanning calorimeter (DSC) are 110° C. or higher. The coating film is an abrasion resistant film whose abrasion resistance measured in accordance with the Taber abrasion testing method is 80 rotations or greater.

摘要： Metallic coat finishing with good gloss vividness is provided by undercoating a liquid coating containing a specified thermosetting vinyl copolymer and a metallic appearance imparting pigment, overcoating a thermosetting, clear powder paint and then baking the two coated film together. The specified thermosetting vinyl copolymer is obtained by copolymerizing N-alkoxymethyl(metha)-acrylic amide, a hydroxyl group containing vinyl monomer, a carboxyl group containing vinyl monomer and copolymerizable other vinyl monomers in specified amounts.

摘要： A resin composition of the present invention is obtainable by adding a photo-polymerization initiator (d) to a resin solution (a) containing a modified product of a thermoplastic resin (A). The modified product is prepared by conducting radical polymerization of the thermoplastic resin (A) with a (co)polymer (B) of a copolymerizable monomer (C) comprising a monomer having an α,β-mono-ethynically unsaturated group, or the monomer and other copolymerizable monomers in a weight ratio (A)1(B) of 1/9 to 9/1, in an organic solvent, or by conducting polymerization of a copolymerizable monomer (C) comprising a monomer having an α,β-mono-ethylenically unsaturated group, or the monomer and other copolymerizable monomers in a weight ratio (A)/(C) of 1/9 to 9/1, in an organic solvent in the presence of the thermoplastic resin (A), and then conducting radical polymerization thereof. A paint including the resin composition and a process for forming a coating film are also disclosed.
