    • A new method is disclosed for the formation of a heat mode image comprising exposing to a heat pattern a donor element comprising a reactant (A) while in contact with an acceptor element comprising a reactant (B), the said reactant (A) being transferred by said exposure from said donor element to said acceptor element to form an image therein by reaction of said reactant (A) with said reactant (B), (2) separating said donor and said acceptor element from each other, and (3) optionally giving said acceptor element a post-treatment consisting of a supply of extra energy, characterized in that the said acceptor element comprises spacing particles also containing a said reactant (B), and/or the said donor element comprises spacing particles also containing a said reactant (A), or a said reactant (B), or a density providing compound, preferably carbon black, or combinations thereof.In the preferred embodiment reactant (A) is a reducing agent and reactant (B) is an organic silver salt, preferably silver behenate. In this case a heat post-treatment on the separated acceptor is performed.The heat pattern is preferably generated by laser exposure.
    • 公开了一种用于形成热模式图像的新方法,包括在与包含反应物(B)的受主元件接触的同时暴露于包含反应物(A)的施主元件的加热图案,所述反应物(A)被转移 通过从所述供体元件暴露于所述受体元件以通过所述反应物(A)与所述反应物(B)的反应形成图像,(2)将所述供体和所述受体元件彼此分离,和(3)任选地 给所述受体元件提供由能量供应组成的后处理,其特征在于所述受体元件包含还含有所述反应物(B)的间隔颗粒,和/或所述施主元件包括还含有所述反应物的间隔颗粒 (A)或所述反应物(B)或提供密度的化合物,优选碳黑或其组合。 在优选的实施方案中,反应物(A)是还原剂,反应物(B)是有机银盐,优选是山嵛酸银。 在这种情况下,对分离的受体进行热处理。 热图案优选通过激光曝光产生。
