PURPOSE:To obtain a composition capable of readily removing with an alkaline water, having excellent weather resistance, water resistance, etc., and used in temporary protection of coating film of car, etc., by blending an aqueous dispersing body obtained by subjecting plural kind of monomers of specific ratio to emulsion copolymerization with an ultraviolet ray absorbing agent, antioxidant, etc., at a specific ratio. CONSTITUTION:The aimed composition obtained by blending (A) an aqueous dispersing agent of copolymer granules obtained by subjecting 100 pts.wt. total amount of monomer containing A1: 7-12 pts.wt. alpha,beta-monoethylenic unsaturated carboxylic acid and A2: 88-93 pts.wt. (meth)acrylic acid alkyl ester having 1-4C alkyl groups to emulsion polymerization and having 2000-20000 number-average molecular weight and -10-40 deg.C glass transition point with (B) 0.1-5 pts.wt. ultraviolet ray absorbing agent, (C) 0.1-5 pts.wt. antioxidant, (D) acrylic thickener and/or natural gums of 0.1-2wt.% based on the total amount of the component A and (E) fluorine based surfactant and/or acetylene based nonionic surfactant of 0.01-6% based on the total amount of the component A. |
