COATING MATERIAL COMPOSITION, CAN COATING MATERIAL CONTAINING THE SAME, AND METAL MATERIAL WITH COATING FORMED BY THE CAN COATING MATERIAL FOR CAN INTERIOR SURFACES

摘要

[Object] To provide a coating material composition having excellent coating workability used particularly for a coating material of interior surfaces of beverage cans and food cans, with which not only crystallization of a coating which causes workability degradation is suppressed but also internal stress can be suppressed and stretchability can be imparted to the coating.;[Solution] A thermosetting resin composition containing 100 parts by weight of a polyester resin composition and 1 to 100 parts by weight of a resole-type phenolic resin (C), the polyester resin composition containing a polyester resin (A) having a glass transition temperature (hereinafter referred to as Tg) of 0° C. or more and a polyester resin (B) having a Tg less than 0° C., in which the weight ratio [(A)/(B)] is 95/5 to 60/40.
