り、外観品質上問題であった。[Prior art] Conventionally, urethane / PVC-based inks have been used as printing inks used for exterior printing such as optical devices such as cameras, acoustic products, home appliances, and gauges for the purpose of quick drying. ing. This urethane / PVC-based ink is obtained by dissolving a vinyl chloride resin in a urethane resin, and has both the properties of urethane and the properties of PVC. That is, it has room temperature drying property and touch drying property by PVC. . The compatibility between urethane and PVC can be changed to free, but the more urethane, the stronger the urethane properties, and the more PVC, the stronger the PVC properties. The preferred modification rate is
About 10% of PVC is denatured. As such a curing agent for urethane / PVC-based inks, isocyanate trimer type polycyclic type having a solid content of 70 to 80% is used, but the pot life (pot life) is as short as less than 4 hours. As the viscosity increased, printability deteriorated, which was a problem in appearance quality.

In the present invention, the condition for selecting the curing agent is that the final performance when the ink is cured at 70 ° C. is equal to or higher than that of the conventional product, and the pot life can be significantly longer than before. . However, in general, when the pot life is lengthened, the physical properties of the printed film often decrease. The dimer isocyanate trimer type monocyclic compound represented by the above general formula (I) in the present invention has a slow reaction rate and a pot life that is about twice as long as that of the conventional one, and does not deteriorate the film physical properties. Efficiency is also improved. In addition, isocyanate groups (NCO
Since the content of-) is about twice, the amount of the curing agent to be used is about half that of the conventional one, which is economical.
