preparing a composition, which forms a coating film having excellent properties after application though the formulation is the same characterized in that 1) a method of producing a composition of an oil-in-water emulsifier type containing a carboxyvinyl polymer optionally alkyl-modified and/or a salt thereof and a nonionic surfactant, wherein an oil-in-water emulsion is prepared at a temperature higher than the cloud point of the nonionic surfactant, the emulsion is cooled to a temperature not higher than the cloud point of the nonionic surfactant, then, a carboxyvinyl polymer is added, and thereafter, the carboxyvinyl polymer is neutralized with an alkaline agent.
