    Abstract: 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.
