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 composition. The slip coating is adherent to the rubber substrate and is very extensible without adverse effect. The synthetic resin slip coating includes from 5 to 90 percent by weight of a first resin copolymer component selected from the group consisting of vinyl chloride-alkyl acrylate copolymer, vinylidene chloride-alkyl acrylate copolymer, and vinyl acetate-alkyl acrylate copolymer, and correspondingly, from 95 to 10 percent by weight of a second resin copolymer component selected from the group consisting of vinyl chloridevinyl ester copolymer, and vinylidene chloride-vinyl ester copolymer.
