阅读说明：本技术 具有热转移图像的泡沫不透明元件 (foamed opaque element with thermally transferred image ) 是由 M.奈尔 D.M.赫里克 于 2018-04-30 设计创作，主要内容包括：可以制备泡沫不透明元件,以在多孔基材的相对外表面和内表面任一者上具有热着色剂图像。该内表面具有作为干燥不透明层布置于其上的干燥泡沫组合物,该干燥泡沫组合物包含：(a)0.1-40重量%的多孔颗粒；(b)至少10重量%的至少部分固化的粘合剂材料；(c)至少0.2重量%的包含表面活性剂的一种或更多种添加剂；(d)小于5重量%的水；和(e)至少0.002重量%的不同于所有的一种或更多种(c)添加剂的不透明着色剂,该不透明着色剂吸收预定电磁辐射。热着色剂图像由来自热供体元件的可升华着色剂的热着色剂转移得到。(the foamed opacifying element can be prepared to have a thermal colorant image on either of the opposing outer and inner surfaces of the porous substrate. The inner surface has disposed thereon as a dry opaque layer a dry foam composition comprising: (a)0.1-40 wt% of porous particles; (b) at least 10 wt% of an at least partially cured binder material; (c) at least 0.2 wt% of one or more additives comprising a surfactant; (d) less than 5 wt% water; and (e) at least 0.002% by weight of an opacifying colorant different from all of the one or more (c) additives, the opacifying colorant absorbing the predetermined electromagnetic radiation. The thermal colorant image is derived from thermal colorant transfer of a sublimable colorant from a thermal donor element.)
