摘要： Resinous polymer sheet material having surface decorative effects. The material is made by applying to a potentially foamable resinous composition (16) a printing composition layer (18) forming a pattern and then applying to said printing composition layer a resinous polymer wear layer (22) having therein reactive polymerizable and cross-linkable monomeric materials. There is included in areas (20) of the sheet material a polymerization initiator, preferably dicumylperoxide, capable of initiating a polymerization and cross-linking reaction of the monomeric materials, and the surface of the wear layer is heated in order to develop the foam, preferably also mechanically embossed, and to bring about such reaction at the areas of the polymerization initiator. The melt viscosity of the wear layer at said areas is thereby increased so that said areas will have a different appearance than the other area of said wear layer.
