    • A method of manufacturing a resin-impregnated printed paper includes applying printed indicia to a paper substrate, impregnating the printed paper with resin and thereafter treating the resin-impregnated printed paper to reduce its water content and to at least partially cure the impregnating resin, whereby to produce a further cured resin-impregnated printed paper. The reduction of water is effected by irradiation with near infrared (NIR) radiation. The paper and/or printed indicia contain one or more pigments selected for their relatively low absorption of NIR radiation and/or a plurality of pigments selected for their mutual relatively low differences in absorption of NIR radiation whereby to minimize localised blistering of the resin arising from any NIR absorption by the pigments. Also disclosed is a décor paper and a laminate.
    • 制造树脂浸渍印刷纸的方法包括将印刷标记施加到纸基材上,用树脂浸渍印刷纸,然后处理浸渍树脂的印刷纸以降低其含水量并至少部分固化浸渍树脂,由此 以生产另外固化的树脂浸渍印刷纸。 水的还原通过用近红外(NIR)辐射照射来实现。 纸和/或印刷标记包含一种或多种颜料,其选择用于它们相对较低的NIR辐射吸收和/或选择用于它们相对较低的NIR辐射吸收差异的多种颜料,由此最小化来自树脂的局部起泡 颜料的任何NIR吸收。 还公开了一种装饰纸和层压板。
