摘要

The present invention includes a polyester resin or a polyurethane resin, and has an acid value (unit: equivalent / 10⁶ G) of 100 or more and 1000 or less, a glass transition temperature of 30 or more and 80 or less, and a number average molecular weight of 5.0 10³ 1.0 x 10⁵ (A1), a polyester resin or a polyurethane resin, and has a glass transition temperature of 0 DEG C or lower and a number average molecular weight of 5.0 x 10 ³ 1.0 x 10⁵ (B) and an epoxy resin (D) having a dicyclopentadiene skeleton. The cured coating film obtained by drying at 130 C for 3 minutes and then heat-treating it at 140 C for 4 hours, And at least a part of at least a part of the thermoplastic resin (A1) and the thermoplastic resin (A2) has a phase-separated structure.
