Composition suitable for obtaining positive images, process for obtaining positive images and images obtained using the same

摘要

there will be a mixture of materials is described, which under irradiation positive images result in and for the production of printing plates and printed circuits is designed. such mixtures of substances containing(i) in an organic solvent soluble strahlungsempfindliches pru00e4polymer, a polyadditions or polykondensationsprodukt from(1) at least one of many carbocyclischen link and / or heterocyclischen connection with at least two additions or kondensationsreaktionen gifted groups r and (2) at leasta polyhydric carbocyclischen link and / or heterocyclischen connection with at least two groups, with the groups r additions or kondensationsreaktionen can take iswith the pru00e4polymer in ortho - or peri position a by implementing a group formed of at least one group (group r coor1 inwherein rl organic rest with one or more double or dreifachbindungen under the irradiation dimerisieren or polymerize, represents, and (ii) 1 to 25% by weight.-%, relative to the weight of the pru00e4polymeren (i), an unsaturated mono - or dicarboxylic formula 1whatr2 is a hydrogen atom or a methyl group, a hydrogen atom or a undr3 via an ester of aromatic or aliphatic mono - or dicarboxylic bound alkylenkette,one or two more groupscan contain.
