Description

Be suitable for the negative graph photosensitive composition of UV-CTP and with the flat stamping version and the planographic printing plate manufacture method of its making
Technical field
The present invention relates to the chemical processing-free negative graph photosensitive composition of a kind of UV-CTP of being suitable for and with the flat stamping version and the planographic printing plate manufacture method of its making.
Background technology
The preparation process of flat stamping version is known by the people in the industry in printing industry.The plate-making process of flat stamping version needed for two steps finished at least, the one, with the forme that has been coated with photosensitive composition by frisket (as, positive type and negative-type frisket) under specific light source, expose, form an optical image latent image therefrom; The 2nd, the forme after the top exposure is carried out a so-called follow-up development step, by this process, remove excess coating.The pre-coating photosensitive lithographic plate is to be the flaky material of support with aluminium or polyester, and can make by above-mentioned two steps and have oleophylic and hydrophilic surface simultaneously, is suitable for lithography.Usually, in a negative-type system, the exposure position becomes the insoluble or indissoluble of developer solution, thereby can in development step the coating at the unexposed position of forme be removed owing to the polymerization or crosslinked the changing of coating.Otherwise in a positive type system, development step is that the expose material at position of forme is removed.Development step generally includes with developer rinsing and washing, develops in a processing unit that contains developer usually.The used developer of positive-type flat stamping version is highly basic normally, also contains organic solvent in the negative type developer solution usually except that highly basic, as phenmethylol etc.Certainly, also useful heating means of the development of optical image or alternate manner are finished.
The shortcoming of above-mentioned two kinds (promptly wet and heat) developing processs be consuming time, cost is very high.And when adopting volatile organic matter or highly basic as developer, the processing of these waste liquids will bring environmental problem.
Along with the development of printing industry and the raising of people's living standard, countries in the world are more and more higher to environmental protection requirement, so just need a kind of forme that before printing, does not need chemical treatment or do not need any processing, this not only can help environmental protection, and this setup time that also will help the space of reducing printing cost, reducing pressroom and reduce presswork.
The structure of the positive type forme that need not handle before the printing after imaging is disclosed (as seeing U.S. Patent No. 5,102,771; 5,225,316 and 5,314,785).These patent disclosures based on the forme and the light acid generation system of the light sensitive layer that contains acrylate or methacrylate polymers.When image is exposed to optical radiation following time, the polymer unwinds in the rayed zone forms water wettability, and keeps ink affinity at the polymkeric substance that is not having light-struck zone.
The pre-coating photosensitive negative-type lithographic plate that need not handle before the printing after imaging also is that this field is known. between imaging and printing, do not need the kind of treatment step forme in U.S. Patent No. 3,231,378; 3,285,745; With 3,409, open in 487. these formes contain a kind of phenolics that comprises, the photosensitive composition of ethylene oxide polymer and light sensitizer. when it is exposed to actinic radiation following time, make phenolics generation oxidation, thereby having increased ink affinity. the shortcoming of these formes is that their ink affinities in printing process easily reduce, so that need the balance between strict China ink/water of controlling on the printing machine could guarantee normal printing, sometimes also can make forme become and can not operate. U.S. Patent No. 3,793,033 discloses added people's hydroxy ethyl cellulose ester in constituent. and the forme of acquisition can not become blind version, and (lithographic plate is not subjected to China ink when promptly printing, image impairment), and only needing to carry out less control to the China ink/water balance on the printing machine. a tangible adverse condition of this composition is to obtain suitable printing machine printing with the phenolics that need solidify. so just need on the printing plate precursor that makes, form a two-layer system, if promptly should add one deck sensitizer layer again containing on the phenolics layer. will decompose when phenolics is in curing so not being coated with the sensitizer layer after the curing.
The another kind of negative-type forme that need not handle at imaging and pressroom is those formes based on the multilayer photographic layer.Usually, as in U.S. Patent No. 4,600,679 and 4,104,072 and European Patent Publication No No.450, described in 199, these structures have a hydrophilic photographic layer at the most close version base, and an extra play that is used for photo-hardening is connected with ground floor.These structures are the hydrophilic layer of the negative-type photosensitive composition on basis as the most close version base in order to the aromatics diazo-compounds usually.A shortcoming of these formes is its trend that scumming (being China ink on the background position) is arranged and pollute printing machine.This shortcoming need be cleaned forme with suitable clean-out system (being fountain solution) earlier before printing. and therefore, the adding of diazo-compounds and resin is harmful to for the forme that is used for " non-processor " version.Disclosed forme among the PCT application number No.93-05446 does not wherein have the diazonium composition in the hydrophilic layer, therefore eliminated because the residual caused printing machine pollution problem of unreacted diazo substance.Described version comprises version/version base, the sensitization polymerization hydrophilic layer of the most approaching version base and one the second photopolymer hydrophobic layer that separates near the version base.The sensitization hydrophilic layer is based on the polymerizable material of diazonium-containing compound not.The functionality of version loses water-soluble under actinic radiation by two layer exposures and sclerosis obtains.This edition only needs a printing machine that China ink and fountain solution are housed with the good printed matter of acquisition after exposure, and do not need to carry out before printing the prewashing version.Because this structure has the outer hydrophobic layer, so just can not obtain performance of ink with edition identical the water of routine if before printing, do not handle the hydrophobic substance of removing background parts.
Summary of the invention
The object of the present invention is to provide a kind of light sensitivity height, redeeming a vow to a god property of site good, can be directly after the ultraviolet light source exposure with the tap water flushing or without any washing processing step promptly be available on the machine printing, also can obtain the chemical processing-free negative graph photosensitive composition that is suitable for UV-CTP of high pressrun and with the flat stamping version and the planographic printing plate manufacture method of its making.
