Abstract

A coating composition for a lubricating coating film includes: (A) a phenolic resin; (B) an epoxy resin having an epoxy equivalent weight of 600 to 4000; and (C) at least one type of solid lubricant. The epoxy equivalent weight is generally defined by the number average molecular weight per the number of epoxy groups in a single molecule. The coating composition has a weight ratio of component (A) to the total weight of component (A) and component (B) of at least 50 weight %. A lubricating coating film, formed from the coating composition, has a high level of flexibility on surfaces of various base materials.
