Abstract
Provided is a paint composition which can give a coating having excellent stretchability and further having excellent contamination resistance. A solvent-based paint composition comprises a fluorocopolymer (I), and an organic solvent (II), the fluorocopolymer (I) including: a perhaloolefin structural unit (a) that contains two carbon atoms, a vinyl acetate structural unit (b), a hydroxyl group-containing vinyl monomer structural unit (c) represented by the following formula (1): CH2═CH—O—(CH2)n—OH wherein n is an integer of 2 or more, and a carboxyl group-containing monomer structural unit (d) represented by the following formula (2): R1R2C═CR3—(CH2)m—COOH wherein R1, R2, and R3 are the same as or different from one another, and each a hydrogen atom or a C1-C10 linear or branched alkyl group; and m is an integer of 2 or more.
