Abstract
Abstract An emulsion of a crosslinking type comprises an oligoester-(meth)acrylate having at least two (meth)acryloyl groups in a molecule, a molecular weight of not more than 1000 per one (meth)acryloyl group, and a boiling point at a normal pressure of at least 200° C and a polymer emulsion of an oil-in-water type.
