| 摘要 |
The present invention provides a thermocurable resin composition for coating with good storage stability and capable of forming a coating film excellent in low temperature curability, acid resistance, scratch resistance etc., containing a polymer obtained by half-esterifying with a monohydric alcohol the acid anhydride group of an acid anhydride group-containing polymer, obtained by copolymerizing a polymerizable, unsaturated, half-esterified product obtained by half-esterification of a hydroxyl group-containing, polymerizable unsaturated monomer and an acid anhydride group-containing compound in the proportion of 1-1.5 moles of the acid anhydride group per 1 mole of the hydroxyl group, an acid anhydride group-containing, polymerizable unsaturated monomer and another polymerizable unsaturated monomer; and a polymer having both hydroxyl group and epoxy group in the molecule.
