Abstract A process for applying emulsion coating material to produce crackle patterns which comprises applying an aqueous emulsion undercoating material having as base material a synthetic resin emulsion containing at least one selected from the group consisting of a water-soluble high molecular weight organic substance and an inorganic substance having high swelling property in excess of the quantity required as emulsion stabilizing agent or dispersant, drying the thus applied emulsion undercoating material, and applying an aqueous emulsion set coating material containing as base material at least one selected from the group consisting of homo- and co-polymer emulsions of acrylic ester, homo- and co-polymer emulsions of methacrylic ester, said emulsion containing silicon dioxide sol.
A process for producing crackle patterns which comprises: A. preparing an aqueous emulsion comprising 50 parts of a 50 percent vinyl acetate-acrylic ester copolymer emulsion, 120 parts of a 3 percent solution of polyethylene oxide and 70 parts of bentonite swelled with water at 20 percent solid content; B. coating aqueous emulsion of A on a substrate and drying said emulsion; C. preparing an aqueous emulsion comprising 50 parts of a 50 percent methyl acrylate polymer emulsion, 50 parts of a 50 percent ethyl methacrylate polymer emulsion and 130 parts of a silica sol containing about 20 percent by weight silicon dioxide, the silica content of emulsion C being at least 3 percent by total weight thereof when set; D. coating the aqueous emulsion of C on said coated substrate of B; and E. drying the coated substrate of D to produce a crackle pattern.
