採用されている。BACKGROUND ART AND PROBLEMS A two-component polyurethane paint consists of a polyol component having two or more hydroxyl groups in one molecule and a polyisocyanate compound having two or more isocyanate groups in one molecule. When these two components are mixed, they easily react and cure at room temperature, so it is necessary to mix these two components immediately before use (painting). The coating film made of this paint is rapidly cross-linked and cured three-dimensionally at room temperature or at a low temperature of 120°C or less, and therefore has excellent weather resistance, physical and chemical properties, etc., and as a result, 2. Liquid-type polyurethane paints are widely used for painting plastics that require low heat distortion temperature and dimensional stability (e.g. automobile exterior panels, bumpers, and other parts) and for repair painting of parts that are difficult to reheat. ing.

とがあり、その結果得られる塗膜の平滑性、鮮映性等が
低下する原因となっている。However, when the above-mentioned two-component polyurethane paints are mixed together, the curing reaction proceeds quickly and the viscosity increases.
Since it turns into a gel, it has a short pot life. Therefore, in industrial painting lines, the paint may thicken from the time the above components are mixed until it reaches the coating machine, which causes a decrease in the smoothness, sharpness, etc. of the resulting paint film. It becomes.

を有している。Methods for extending the pot life of two-component paints include, for example, ■ Adding a small amount of an acid component (negative catalyst) such as butyl phosphate, ■ Adding a ketone solvent (such as methyl ethyl ketone, methyl isobutyl ketone, etc.). , a method of suppressing the curing reaction of the same components by forming a coordinate bond between an isocyanate group and a carbonyl group has been studied. However, with the above method (■), it is difficult to extend the pot life to a practical level, and it may even increase the viscosity. The desired effect may not be achieved and the viscosity of the paint may therefore be lower than the optimum coating viscosity;
It has defects such as insufficient painting workability and finish quality for practical use.
