    Abstract: PROBLEM TO BE SOLVED: To obtain an emulsion low in rain drop pollutivity and large in initial water resistance. SOLUTION: 95-30 pts.wt. of a 1-12C acryl group-containing (meth)acrylic acid alkyl ester, 5-70 pts.wt. of styrene, 0.5-10.0 pts.wt. of an unsaturated carboxylic acid, and 0.5-10.0 pts.wt. of an amide group-containing acrylic monomer and emulsion-copolymerized in the presence of a polymerizable anionic surfactant and a polymerizable nonionic surfactant in a total amount of 0.5-10.0wt.% based on the whole monomer amount to obtain the low pollution type emulsion used for single layer elastic coating materials and having a glass transition point of -20 to 30 deg.C.
