ABSTRACT:
A method of making a differential gloss product which comprises: forming a gelled, potentially foamable, base resinous material; printing thereon a predetermined pattern, some portions containing a urethane polymerization catalyst and either the same or other portions containing a foaming inhibitor; applying to the printed pattern a resinous wear layer; gelling the resinous wear layer and foaming and fusing the resinous materials; applying a urethane coating composition containing no urethane polymerization catalyst to the resinous wear layer; heating to polymerize the portions of the urethane coating composition lying directly over the portions containing the urethane polymerization catalyst to create interspersed high gloss polymerized surfaces; dusting onto the entire surface of the urethane coating composition a powdered particulate or granular material containing a urethane polymerization catalyst; removing the excess particulate or granular materials from the interspersed, polymerized, high gloss areas; and heating to polymerize the remaining surfaces of the urethane coating composition to create thereat low gloss surfaces due to the presence of the occluded particulate or granular materials therein.
