Water-based coating agent composition, water-based lubricating coating composition and member comprising the same

摘要

The present invention addresses the problem of providing an aqueous coating agent composition (in particular, an aqueous lubricating film paint composition that includes a solid lubricant) that suppresses the interaction of a curable resin and a surfactant, suppresses thickening/disproportionation throughout an aqueous coating agent, has superior overall fluidity, coating properties, and storage stability, and can form a favorable coating film, along with the problem of providing a member provided with said coating film, as well as a method for forming said coating film. Said problems can be solved by an aqueous coating agent composition that includes (A) a curable resin in the form of an aqueous emulsion, (B) a surfactant, (C) solid particles, (D) one or more nitrogen-containing heterocyclic compounds, and (E) water. In particular, the component (C) preferably includes a solid lubricant, and for reasons of environmental regulations, it is particularly preferable that the component (D) be 1,3-dimethyl-2-imidazolidinone.
