1. 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.
