Abstract (en)
[origin: EP0978376A2] 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, a betaine or betaine anionic cyanine dye (I) with a pyrimidin-2,4,6-trion-6-yl-substituted (poly)methin group. 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, a betaine or betaine anionic cyanine dye of formula (I): with a pyrimidin-2,4,6-trion-6-yl-substituted (poly)methin group; 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 or 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; A = C or a chain with conjugated double bonds forming a delocalized pi -electron system between the quaternary nitrogen (N) atoms of the 3H-indolium, quinolinium or benzothiazolium group and the enolate oxygen (I) atom of the pyrimidin-2,4,6-trione group.
