PURPOSE: A resin composition for top coating of automobiles is provided which improves cross-linking velocity, pigment dispersion and storability and is excellent in compatibility. CONSTITUTION: A composition comprises 10 to 50% by weight of ε-caprolacton modified hydroxyl monomer of formula 1 in which R1 is H or methyl, n is an integer from 2 to 4., 3 to 30% by weight of amine modified dihydroxy monomer of formula 2 in which R1 is H or methyl, n is an integer from 2 to 5, and 10 to 86% by weight of acryl monomer. The paint prepared with the resin composition is excellent in compatibility, cracking resistance, weather resistance, chemical resistance, and water resistance. |
