Abstract
The present invention provides an aqueous coating agent including a vinyl polymer (A) having a basic nitrogen atom-containing group and a carboxylic group, a quaternary ammonium salt (B), and an aqueous medium (C). Particularly, the present invention provides an aqueous coating agent including a compound represented by General Formula (1) below as the quaternary ammonium salt (B). The aqueous coating agent has excellent adhesiveness, warm water resistance, corrosion resistance, and chemical resistance, and can form a film that is capable of preventing the deterioration of various substrates. In General Formula (1), R1 to R4 each independently represent an alkyl group having 1 to 20 carbon atoms or an aryl group.
Claims21
An aqueous coating agent comprising:
- a vinyl polymer (A) having a basic nitrogen atom-containing group, which is at least one selected from an N,N-dimethylaminoethyl group, an N,N-dimethylaminopropyl group and an N,N-diethylaminopropyl group, and a carboxylic group;
- a quaternary ammonium salt (B) represented by General Formula (1) below;
- an aqueous medium (C);
- and
- a nonionic emulsifier (D),
- wherein the nonionic emulsifier (D) is a polyoxyalkylene branched decyl ether:
- wherein, in General Formula (1), R1 to R4 each independently represent an alkyl group having 1 to 20 carbon atoms or an aryl group.
