Emulsion and process for producing the same

摘要

An object of the present invention is to provide emulsions that can favorably be used for exterior paints and that can form fine films excellent in various physical properties such as weathering resistance, water resistance and alkali resistance. This object of the present invention can be attained by a process for producing an emulsion, comprising preparing a monomer composition that comprises as essential components a (meth)acrylic ester, a dialkyl (meth)acrylamide or styrene (the amount of the styrene being from 0.1 to 20% by weight of the (meth)acrylic ester), and a surfactant, and subjecting the monomer composition to emulsion polymerization to form an emulsion.
