    摘要： Described herein is a topcoat paint composition having an acrylic resin (A) and a melamine resin (B). The acrylic resin (A), relative to 100 parts by mass thereof, contains 30-40 parts by mass of 2-hydroxyethyl methacrylate, 10-30 parts by mass of styrene and 25 parts by mass or more of 2-ethylhexyl acrylate, and does not contain, relative to 100 parts by mass of the acrylic resin (A), more than 5 parts by mass of caprolactone compound(s) and/or hydroxy group-containing (meth)acrylates constituted of 7 or more carbons. The content of acrylic resin (A), relative to 100 parts by mass of total resin solids of the topcoat paint composition, is 45 parts by mass or more. The content of melamine resin (B), which does not contain complete alkyl ether type melamine resin, relative to the acrylic resin (A), as resin solids ratio, is acrylic resin (A)/melamine resin (B)=50/50 to 80/20.

    摘要： To provide a single-liquid type clear paint composition which has an excellent paint film appearance, and with which in particular which a good paint film appearance is obtained in the 3C1B system multi-layer paint film forming method, with which paint films which have excellent water resistance and weather resistance can be obtained, which has a high solid fraction on coating and which has good storage stability. [Means of Resolution] A single-liquid type paint composition which has as essential components a hydroxyl group-containing polyester resin (A) of which the weight average molecular weight is from 1,500 to 8,000, the acid value is from 0 to 50 mgKOH/g, the hydroxyl group value is from 100 to 180 mgKOH/g and the glass transition temperature is from -30 to 0°C and a crosslinking agent (B) which reacts with hydroxyl groups, wherein the aforementioned (A) component is a hydroxyl group- containing polyester resin which has been obtained by reacting a polybasic acid (a), a polyhydric alcohol (b) and at least one type of component (c) having at least six carbon atoms selected from among the saturated mono-carboxylic acids, saturated mono-alcohols, saturated glycidyl ethers and saturated glycidyl esters where the proportion by mass of the aforementioned (c) component is from 20 to 60 mass% with respect to the sum of the solid fraction masses of the aforementioned (a) to (c) components.
