APPLICATION: JP 1995-91570 24 Mar 1995. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The title material comprises a photosensitive image forming layer on a support via a peelable (cushion) layer, where the image forming layer is capable of being transferred onto an image-receptor and the material satisfies a specific image-brightness relation and a specific image color relation (CIELAB). The photosensitive image-forming layer may contain 1,2-naphthoquinonediazido-4-sulfonyl chloride and/or 1,2-naphthoquinonediazido-5-sulfonyl chloride, a photoinitiator, a carboxylic acid vinyl ester polymer, a novolak resin.In this experiment, several chemicals are used like 36451-09-9 and 26355-01-1 The image-forming layer may contain photopolymerizable microcapsules. .

Developer solution for photosensitive printing plates

Developer solution for photosensitive printing plates. Matsumoto, Hiroshi (Fuji Photo Film Co., Ltd. , Japan). Ger. Offen. DE 3315395 A1 3 Nov 1983, 16 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: G03F007-08. APPLICATION: DE 83-3315395 28 Apr 1983. PRIORITY: JP 82-72913 30 Apr 1982.In this article, certain chemicals are used. Some of their cas registry numbers are 1312-76-1 and 36451-09-9 DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A developer soln. for o-quinonediazide printing plates which does not form insol. residues which clog the sprayer holes consists of an alkali silicate soln. and a chelating agent for Ca and/or Mg which is selected from aminopolycarboxylic, org. phosphinic, and phosphonotricarboxylic acids. Thus, an oxidized Al plate was coated with a soln. of a 1,2-naphthoquinone-2-diazide-5-sulfonic acid ester of an acetone-pyrogallol resin, HCHO-p-octylphenol resin, a cresol-HCHO resin, 1,2-naphthoquinone-2-diazide-4-sulfonyl chloride, and tetrahydrophthalic acid anhydride in 2-methoxyethyl acetate and MeCOEt to 2.5 g/m2. The plate was exposed and then spray developed with a dild. soln. of K silicate, KOH, and NTA Na salt. This was repeated using the same soln. for 20 days without clogging the sprayer holes. .
