  A thermal-dye-bleach construction comprising a dye in association with a thermal dye-bleaching agent of general formula I: ##STR1## wherein: each of R.sup.a and R.sup.b are individually selected from: hydrogen, an alkyl group, an alkenyl group, a cycloalkyl group, an aralkyl group, an aryl group, and a heterocyclic group, and preferably, both R.sup.a and R.sup.b represent hydrogen; p is one or two, and when p is one, Z is a monovalent group selected from: an akyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, and a heterocyclic group, and when p is two, Z is a divalent group selected from: an alkylene group, an arylene group, an alkenylene group, an alkynylene group, an aralkylene group, a cycloalkene group, and a heterocyclic group; and, M.sup.+ is a cation which will not react with a carbanion generated from the thermal-carbanion-generating agent in such manner as to render the carbanion ineffective as a bleaching agent for the dye.

  Certain poly(lactic acid) and poly(glycolic acid) polymers or copolymers, and certain carbonates, lactones, lactates, lactylates, lactides, glycolates, glycolylates, and glycolides have been found to stabilize thermal-dye-bleach constructions containing a dye in association with a thermally-generated-bleaching agent. Preferably, the thermally-generated-bleaching agent is a thermal-carbanion-generating agent such as a quaternary ammonium salt of a phenylsulfonylacetic acid or a thermal-nucleophile-generating agent such as an ammonium salt of a phenylsulfonylacetic acid. These materials have been found to be particularly effective when used in acutance and antihalation systems for photothermographic and photographic elements.

  某些聚乳酸和聚乙二醇酸聚合物或共聚物，以及某些碳酸酯、内酯、乳酸盐、乳酸酯、乳酸内酯、乙二醇酸盐、乙二醇酰酸盐和乙二醇内酯被发现可以稳定热染料漂白结构，其中包含染料和与热产生漂白剂相结合。首选的热产生漂白剂是热产生羧阴离子生成剂，例如苯基磺酸乙酰氨基甲基铵盐，或热产生亲核剂生成剂，例如苯基磺酸铵盐。这些材料在光热印相和摄影元件的锐度和抗光晕系统中使用时特别有效。
