PURPOSE:To provide the title temporary coating compsn. which has excellent coating applicability, peelability and corrosion preventive properties, and which is obtd. by adding a lubricant, a sensitizer, etc., to a particular monomer mixture contg. (meth) acryloylmorpholine. CONSTITUTION:A product (A) obtd. by reacting 1 mol of a compd. having one oxirane ring with 0.8-1.1mol of an alpha, beta-ethylenically unsatd. carboxylic acid having one carboxyl group, followed by reaction with 0.5-1mol of a polybasic acid (anhydride) or (and) a product (B) obtd. by reacting 1mol of a (meth) acrylic ester having a terminal hydroxyl group with 0.8-1.1mol of a polybasic acid (anhydride) is provided. 100pts.wt. said product is mixed with 5-100pts.wt. (meth) acryloylmorpholine of the formula (wherein R is H or methyl). Added to 100pts.wt. monomer mixture thus obtd. are 1-30pts.wt. lubricant and optionally 0.5-20pts.wt. sensitizer, thereby obtaining the title compsn. |
