Patent ID: 7378043

Claim:
A method of making a latex article with a geometrically defined surface texture, which method comprises: dipping a smooth former into a polymeric coagulant composition comprising a water-soluble polymer, a polyglycol, a surfactant, and a coagulating salt; drying the polymeric coagulant composition to form a tacky, polymeric coagulant coating; applying discrete coagulant particles to the tacky, polymeric coagulant coating; dipping the former into a coagulatable aqueous latex emulsion, and destabilizing the latex emulsion in close proximity to the former, thereby forming a coagulated first latex layer that covers the discrete coagulant particles and external surface of the former; heating the former to form a first cured latex layer by vulcanization or curing; stripping and inverting the first cured latex layer to expose the discrete coagulant particles; and leaching or dissolving the discrete coagulant particles in water or an appropriate solvent; whereupon the latex article with the geometrically defined surface texture is obtained.
