Abstract
A highly weather-resistant, single package, cross-linkable emulsion using an emulsion polymer (X) obtained by emulsion polymerization, in an aqueous medium, of polymerizable monomer ingredients (II) comprising (a) from 0.1 to 10% by weight of a polymerizable UV-ray stable monomer, (b) from 5 to 99.4% by weight of cycloalkyl group-containing polymerizable monomer, (c) from 0.5 to 40% by weight of a polymerizable monomer which contains the groups having reactivity with carboxyl groups and (d) from 0 to 94.4% by weight of other polymerizable monomer, in which the amount of the polymerizable monomers (a), (b), (c) and (d) in total is 100% by weight, by using a water soluble or water dispersible polymer (I) having a terminal alkyl group with an acid value of 200 or greater obtained by polymerizing a polymerizable monomer ingredient (A) containing an unsaturated carboxylic acid as an essential ingredient under the presence of an alkyl mercaptan of 6 to 18 carbon atoms. This emulsion provides a highly weather-resistant, single package, crosslinkable emulsion capable of forming a coating layer which rapidly dries to cure at the initial stage of coating, exhibits long lasting excellent wate…
