Abstract

PURPOSE: To provide the titled compsn. which has excellent storage stability and produces an excellent coating film when baked and cured at a low temperature and in a short time, containing a polyisocyanate blocked by ethyleneimine and a polyol resin having a softening point of not lower than a specified temperature.
CONSTITUTION: There is provided a compsn. contg. an ethyleneimine-blocked polyisocyanate (A) [obtained, by the reaction of a polyisocyanate (e.g. trimethylene diisocyanate) with ethyleneimine in the presence of a solvent having no active hydrogen or in the absence of a solvent by a conventional method] and a polyol resin (B) having a softening point of not lower than 40°C (e.g. a polyester resin having a MW of 500W5,000, a hydroxyl number of 10W300, an acid value of 1W 100 and a softening point of 60W130°C). The compsn. is extremely stable druing storage without causing gelation, and can be baked and cured at a low temp. of not higher than 130°C. The scattering of the blocking agent does not occur. The resulting coating film has good physical performance without causing scorching or foaming.
