Wässrige Dispersion einer abziehbaren Beschichtungszusammensetzung
摘要
<p>The aqueous dispersion of a peelable coating composition of the present invention is (a) a mixture containing 5-40% by weight of an emulsion of an acrylic copolymer having a glass transition temperature (hereinafter referred to as "Tg") of not lower than 40 DEG C, and 95-60% by weight of an emulsion of another acrylic copolymer having a Tg ranging from -20 DEG C through 5 DEG C. The acrylic copolymer emulsion mixture (b) contains ethylenically unsaturated vinyl monomers having acid value in a total amount of 0.5-1.0% by weight, and (c) at least one of the acrylic copolymer emulsions is an acrylic copolymer which has been polymerized by use of a reactive surfactant, and (d) the particle size of the acrylic copolymer emulsions is not more than 200 nm.</p>
