Abstract
A method for making a vinyl chloride resin sheet having a raised pattern thereon. The method comprises the steps of providing an open-celled vinyl chloride resin sheet and printing a portion of the sheet with a composition comprising a cross-linkable compound in accordance with the pattern to be formed. The printed sheet is then dried and subsequently heated to a temperature higher than its softening temperature whereby the open-celled unprinted portion of the sheet is depressed and whereby the printed pattern remains open-celled and stands in relief with respect to the depressed portion.
