• Novel developing agents for (photo) thermographic systems

  公开（公告）日：1995-11-08

  A thermographic element comprising in a non-aqueous binder medium a silver salt oxidising agent in reactive association with a compound comprising a plurality of redox colour releasing moieties such that oxidation of each redox colour releasing moiety causes release from said compound of a thermally diffusible dye. The compounds many of which are new incorporate two or more developer moieties into a single molecule to minimise the diffusibility of the compound. Following oxidation, either directly by the silver salt or by means of a cross-oxidising agent, each oxidised developer moiety releases a thermally diffusible dye. The compounds are of sufficient size and molecular weight to slow or prevent diffusion in imaging systems and yet possess several active developer moieties per molecule which is advantageous over known ballasted dye releasers which comprise bulky molecules with only a single developer moiety.

  一种热成像元素，包括在非水性粘合剂介质中，一种银盐氧化剂与含有多个氧化还原色释放基团的化合物反应地结合，使得每个氧化还原色释放基团的氧化引起所述化合物中的热扩散染料的释放。这些化合物中的许多是新的，将两个或更多的显影剂基团结合到一个分子中，以减少化合物的扩散性。在氧化后，通过银盐直接氧化或通过交叉氧化剂，每个氧化的显影剂基团释放出一个热扩散染料。这些化合物足够大且具有足够的分子量，以在成像系统中减慢或阻止扩散，但每个分子中具有多个活性显影剂基团，这比已知的只包含单个显影剂基团的笨重分子的配重染料释放剂更具优势。
