Abstract
A releasable aqueous coating composition used for temporarily protecting a finished coating film coated on an automobile body. It contains (A) an aqueous acrylic resin obtained by copolymerizing a monomer mixture of a (meth)acrylic ester monomer as an essential component and other polymerizable unsaturated monomer, except for (meth)acrylonitrile, as an optional component, and having a glass transition temperature of 5.degree. to 30.degree. C. and a weight average molecular weight of 20,000 or more, (B) an ultraviolet light absorber, and (C) a water repellent material. A method of temporarily protecting the finished coating film on the automobile body by coating the releasable aqueous coating composition onto a surface of a finished cured coating film coated onto the automobile body.
