<p>1287177 Coated sheet material ETABS MARECHAL 30 Sept 1970 [15 Oct 1969] 46516/70 Heading B2E [Also in Divisions B5 and B6] Decorative surface coverings are obtained by depositing on a surface support layers of differently coloured plastisols, these being coloured either beforehand or in situ, containing one or more homopolymers or copolymers of vinyl chloride, the layers being deposited one above the other before the previous layer is dry, blowing air or other gas towards the surface on which the plastisols have been deposited and subsequently heating to cause gelling. The layers may be applied to a band from which it may be removed or to a permanent substrate such as a woven, knitted or non-woven fabric. Pre-treatment to improve adhesion may be necessary, e.g. degreasing of metals. The plastisols may contain decorative elements such as coloured beads, scales -and fibres. The layers may be applied by spraying, pouring, dipping or coating with a doctor blade. Organic liquids which form occlusions during the gelling may be added to the plastisols and the layers may be embossed, and/or printed.</p> |
