Abstract
Methods for producing bodies having chemically embossed patterns comprise: (1) adding sulphur and synthetic rubber material capable of forming sulphur bridges to a vinyl chloride resin preparation containing a foaming agent, forming the mixture into a sheet, printing embossed patterns on the sheet using an ink containing a vulcanization accelerator, drying the printed sheet and then heating the sheet to decompose the foaming agent thereby foaming the sheet; and (2) adding synthetic rubber material containing terminal groups capable of reacting with isocyanates to a vinyl chloride resin preparation containing a foaming agent, forming the mixture into a sheet, printing embossed patterns on the sheet using an ink containing isocyanates, drying the printed sheet and then heating the sheet to decompose the foaming agent thereby foaming the sheet.
