Abstract
The use of a sulfoalkyl monomer in monovinylidene aromatic/(meth)acrylate/(meth)acrylic acid monomer latexes has been found to provide surprisingly good combinations of ion stability and moisture resistance. This is shown to be especially beneficial in paper coating and paint formulations. In examples, sulfopropyl methacrylate has proven especially beneficial in a styrene/n-butylacrylate/methacrylic acid latex for use in industrial-type, high strength coatings and formulations for coating offset printing paper.
