<p>This invention relates to a peelable coating water composition which is used to temporarily protect a film of coating on a shell plate of an automobile, and which contains a water acrylic resin (A) having a glass transition temperature of 5-30 °C and weight average molecular weight of not less than 20.000 and obtained by copolymerizing a monomeric mixture in which (meth)acrylic ester monomer is an essential component, and in which polymerizable unsaturated monomers except (meth)acrylonitrile are added to the (meth)acrylic ester monomer as necessary, and an ultraviolet ray absorbent (B); and a method of temporarily protecting a film of coating on a shell plate of an automobile, characterized in that this peelable coating water composition is applied to a surface of a finishing cured film of coating formed on a shell plate of an automobile. According to the temporary protection method of the present invention, the commercial value of a film of coating formed on the shell plate of an automobile can be maintained for a long period of time, and the protective film can be peeled off simply manually or with a high-pressure water current before the automobile is delivered to a consumer. The removed film of coating can be burnt with no noxious gas generated therefrom.</p> |
