CODEN: GWXXBX. CLASS: IC: B41M005-18; C23C013-04; C03C017-42. APPLICATION: DE 83-3319738 31 May 1983. PRIORITY: JP 82-92634 31 May 1982; JP 82-111549 30 Jun 1982; JP 82-153861 6 Sep 1982. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A multilayer heat-sensitive optical recording structure with high light sensitivity which gives multicolored images of high resoln. 89918-26-3 and 26206-78-0 are cas registry numbers of chemicals which are used as reagents here. and contrast consists of a support which is transparent to visible light into the near-IR region, a color agent coating on the support contg. leuco dyes, a light-absorbing layer for a sp. wavelength, on the dye layer, and a developer layer composed of a transparent solid acid. The layer structure may contain several color-agent coatings each assocd. with a light-absorbing layer with wavelength selected for the underlying leuco dye. Thus, a glass support was coated in a Ta boat under a pressure ￡10-5 torr with Crystal Violet Lactone 2.0 m, a light-absorbing layer, and phenolphthalein to give a plate which can be used to give blue images when contacted with a thermal printing head. .
