Abstract (en)
[origin: EP0978375A2] Positive radiation-sensitive mixture containing a water-insoluble organic polymeric binder, which dissolves or at least swells in aqueous alkaline solution, contains, as infrared (IR)-absorbing dye, an anionic penta- or hepta-methin cyanine dye (I). Positive radiation-sensitive mixture containing a water-insoluble organic polymeric binder, which dissolves or at least swells in aqueous alkaline solution, contains, as infrared (IR)-absorbing dye, an anionic penta- or hepta-methin cyanine dye of formula (I), which contains 2-4 sulfonate, carboxylate and/or phosphonate groups but a total of no more than 2 sulfonate groups; n = 2 or 3; R<1-8> = hydrogen (H), R or 6-10 C aryl, optionally mono- or poly substituted by R; R = halogen, sulfonate, carboxylate, phosphonate, hydroxyl (OH), 1-4 carbon (C) alkoxy, nitro, amino, mono- or di-(1-4 C alkyl)-amino; R<9>, R<10> = linear or branched 1-6 C alkyl, 7-16 C aralkyl or 6-10 C aryl, optionally mono- or poly substituted by R; R<11>, R<12> = optionally substituted 1-4 C alkyl or 6-10 C aryl; Z<1>, Z<2> = sulfur (S), di-(1-4 C alkyl)methylene or ethen-1,2-diyl; X<-> = an anion.
