摘要

The precursor composition, lithography for imaging lithographic printing precursor, so as to play eletru00c8nica causticising or precursor to doping, use in the printing of a lithographic printing form precursor for use in manufacturing or ask him Tru00c8nica a precursor to play eletru00c8nica a precursor to play eletru00c8nica,Use in a coating with image formation of a polu00ecmero containing hydroxyl groups and one or more agents, method of preparation of a precursor to lithography, salt, salt of a cation of fosfu00c8nio and a u00e1nion of carboxylate or sulfonate alkyl or arila and salt of a cation Of triarylmethane and an anion of carboxylate or sulfonate.It is a composition which comprises a polymer containing hydroxyl groups, and the composition is suitable as a coating for lithography, a precursor with image formation of IV, in which the composition comprises one or more agents: (a) absorb the radiation of compri Regulation of wave IV more than 800 nm, and consequ00faentemente,Generate heat; (b) works as a insolubilizador which inhibits the dissolution of the regions without image of the coating in a revealing.But allows the dissolution of the regions with image during development; and (c) increases the inhibition for the dissolution of the regions without image and / or the dissolution of the regions with image to improve the contrast ratio of dissolution (DCR) of the regions without image / image; The agent which executes the function (c) comprises a portion which has a hydrophobic and ionic character.This composition can provide an excellent selectivity with respect to the dissolution rates in revealing, as between areas with and without image image, while the energy required to achieve this differentiation (or "operation speed") is not impaired.
