Aqueous coating agent composition and a coating composition for an aqueous lubricating film comprising the same

An aqueous coating agent composition comprising:

• (A) A curable resin in the form of an aqueous emulsion,
• (B) 0.1 to 50 parts per mass of a surfactant per 100 parts per mass of a solid component of Component (A),
• (C) 5 to 200 parts per mass of solid particles per 100 parts per mass of a solid component of Component (A),
• (D) 1 to 20 parts per mass of one or more types of nitrogen-containing heterocyclic compounds per 100 parts per mass of a solid component of Component (A),
• (E) 0.1 to 10 parts per mass of a film-forming silicone in the form of an aqueous emulsion per 100 parts per mass of a solid component of Component (A), and
• (F) 50 to 1,000 parts per mass of water per 100 parts per mass of a solid component of Component (A),
• wherein at least part of the aforementioned Component (C) corresponds to a solid lubricant,
• wherein Component (D) specified above corresponds to a nitrogen-containing heterocyclic compound represented by any one of Structural Formulas (D-1) through (D-3) given below
• wherein R1 corresponds to a hydrogen atom or alkyl groups each independently having 1 to 9 carbon atoms, and n is a number ranging from 1 to 10, and
• wherein Component (E) corresponds to a film-forming silicone in the form of an aqueous emulsion comprising 100 parts per mass of (Ea) a polyorganosiloxane having at least two hydroxyl groups or hydrolyzable groups bonded to a silicon atom per molecule, 0.1 to 200 parts per mass of (Eb) colloidal silica, 1 to 100 parts per mass of (Ec) ionic surfactant, 0 to 50 parts per mass of (Ed) nonionic surfactant and 10 to 5,200 parts per mass of (Ef) water.
