<p>A resin composition, which comprises (a) a copolymer containing isocyanate group prepared by subjecting a compound represented by the general formula <CHEM> wherein R1 stands for hydrogen or methyl group and an ethylenic unsaturated monomer to copolymerization, and (b) a copolymer containing amino group prepared by subjecting a compound represented by the general formula <CHEM> wherein R2 stands for hydrogen or methyl group and an ethylenic unsaturated monomer to copolymerization, has a pot life of such an extent as for permitting them to be used as spray-coating, and the resulting film is excellent in flexibility, chemical resistance, water resistance and corrosion resistance, and, besides, rapid in curability, thus being useful as cold-drying coatings on metals, plastics, woods, inorgainc materials, etc. and also as adhesives, etc. The resin composition is very good in compatibility, thus being useful in such a field as required high gloss and beautiful finish. Further, the amino group containing copolymer is of relatively high molecular weight, thus being of less toxicity, and, besides, substantially odorless, and, therefore, it causes no injurious problems to health and safety.</p> |
