PURPOSE:To provide the titled composition giving excellent processability and rust-preventive property, by adding specific amounts of a lubricant and a sensitizer to the reaction product of an oxirane ring-containing compound and a carboxyl group-containing alpha,beta-ethylenic unsaturated carboxylic acid, etc. at a specific ratio, or a mixture containing said reaction product. CONSTITUTION:The objective composition can be prepared by mixing (A) (i) 100pts.wt. of a product obtained by (1) reacting 1mol of a compound containing one oxirane ring (e.g. phenyl glycidyl ether) with 0.8-1.1mol of an alpha,beta-ethylenic unsaturated carboxylic acid having one carboxyl group (e.g. acrylic acid) and (2) reacting the product with 0.5-1mol of a polybasic and/or its anhydride, or (ii) 100pts.wt. of the mixture of 100pts.wt. of the component (i) and <=100pts.wt. of an acrylic acid ester and/or methacrylic acid ester, (B) 1-30pts.wt. of a lubricant, and if necessary, (C) 0.5-10pts.wt. of a sensitizer. EFFECT:The coating film can be removed with weak alkaline liquid. |
