ABSTRACT:
Disclosed is a paint for a can which comprises an epoxy resin component formed by condensation of a dihydroxyl compound with an epihalohydrin and a curing agent component, said epoxy resin component containing terminal .alpha.-glycol groups at a concentration of 0.05 to 0.60 equivalent per Kg of the resin.
This paint provides a coating capable of retaining a high adhesion even with the lapse of time and resisting a severe treatment such as retort sterilization.
When this paint is applied to a bonded can, leakage of the content from the side seam with the lapse of time can be effectively prevented. When this paint is applied to a can provided with an easy-open can lid, occurrence of the enamel feather can be prevented at the time of opening the lid.
