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.
具有表面装饰效果的树脂聚合物片材。该材料的制作方法是:在可能发泡的树脂组合物(16)上涂上形成图案的印刷组合物层(18),然后在所述印刷组合物层上涂上树脂聚合物耐磨层(22),该层中含有可反应聚合和交联的单体材料。在片状材料的区域(20)中有聚合引发剂,最好是过氧化二二甲苯,能够引发单体材料的聚合和交联反应,耐磨层的表面被加热,以形成泡沫,最好也是机械压花,并在聚合引发剂的区域产生这种反应。这样,耐磨层在上述区域的熔体粘度就会增加,从而使上述区域的外观与耐磨层的其他区域不同。
