[PROBLEMS] A resin for paint having good storage stability and excellent in various paint properties such as curability at low temperature (80 ° C. or lower), coating appearance, adhesion to various substrates, and weather resistance. A composition is provided. A silane group-containing acrylic resin (P) having a number average molecular weight of 500 to 80,000 having an alkoxysilane group in a side chain obtained by copolymerizing an alkoxysilane group-containing unsaturated monomer (a), and an epoxy group-containing unsaturated resin Number average molecular weight of 5 having an epoxy group on the side chain where the monomer (b) is copolymerized Acrylic resin containing epoxy group of 00-80000 (Q) And a curing agent (B) and a nonionic surfactant (C). A resin composition for a paint, wherein the amount of the saturated monomer (b) is less than 5000 ppm. |
