Abstract
Abstract Rubber articles, such as surgeon''s gloves, are provided with a synthetic resin slip coating by contacting the rubber surface with a synthetic resin latex. The synthetic resin is a vinyl chloride-alkyl acrylate copolymer or a vinylidene chloride-alkyl acrylate copolymer, for example, vinyl chloride-butyl acrylate copolymer. An excellent slip surface is thereby given to the rubber article. Accordingly, when the inner surface of a surgeon''s glove is so treated, the glove is easily put on and taken off.
