ABSTRACT:
Foamed bodies having chemically embossed patterns are prepared by a first method comprising forming a composition containing a vinyl chloride resin, a synthetic rubber material capable of forming sulfur bridges, a blowing agent, a vulcanizing agent (sulfur) and a vulcanization promotor (metal oxide) into a sheet, printing an ink containing a vulcanizing accelerator into a desired configuration onto the sheet, drying and curing the printed sheet and then heating the sheet to decompose the blowing agent thereby foaming the sheet; and a second method comprising forming a composition containing a vinyl chloride resin, a synthetic rubber containing terminal groups capable of reacting with an isocyanate, and a blowing agent, printing an ink containing an isocyanate into a desired configuration onto the sheet, drying the printed sheet and then heating the sheet to decompose the blowing agent thereby foaming the sheet.
