Description
Technical field
The present invention relates to the photographic layer coating fluid, say so more specifically, promptly coat a kind of precoating type sensitization coating fluid on the aluminum substrate of sand screen mesh about making the sensitization coating fluid of PS version usefulness.
Background technology
The PS version claims pre-coating light sensitive plate (pre-sensitised plate) again, and it is prefabricated sensitization liquid to be coated on the version base of hydrophilicity-imparting treatment the lithographic plate that drying is made after handling.The height of PS version quality is not only relevant with its photosensitive property, and closely related with its apparent mass.
In general, when making the PS version, be applied to the sensitization coating fluid through on the aluminum substrate of hydrophilicity-imparting treatment by variety of way.The coating machinery that adopts have single sheet type, also the reel continuously acting production lines arranged.The coating method that adopts has: get rid of be coated with, dip-coating, scraper coating, scraper coating, airblade coating, steel rider be coated with (smooth roll, anilox roll), extrusion coated, sloping flow coat cloth and the curtain coating etc. that falls.Wherein use comparatively generally, be coated with the speed of a motor vehicle and also be not quite similar from 3-100 meters/minutes with steel rider coating and extrusion coated mode.
Along with developing rapidly of press, the demand of PS version is also rising significantly.Therefore, numerous PS version manufacturers is also improving the speed of a motor vehicle hand and foot, to reach the purpose that improves productive capacity.Yet, along with the raising of the speed of a motor vehicle, various apparent disadvantages can appear, as grow dim, lateral road etc., this can seriously influence the yield rate of PS version.The generation of these disadvantages and coating method, drying mode, plant equipment etc. have direct relation, and certain and coating fluid also has confidential relation.If the transformation by coating method, drying mode, plant equipment aspect solves these problems, can impact existing production, and can spend sizable expense.
Summary of the invention
The purpose of this invention is to provide a kind of adapt to the coating of the high speed of a motor vehicle and do not have grow dim, take off be coated with, the positive PS printing plate light sensitive coating fluid of apparent disadvantage such as lateral road.
For achieving the above object, the present invention adopts following technical scheme: positive PS printing plate light sensitive coating fluid of the present invention, it comprises one or more linear phenolic resin, one or more optical light sensitive adhesive, one or more dye well solvent, and contains the compound of following structure I.
Compound I
Wherein:
The R1 representative contains hydrophilic groups such as hydroxyl, amide group, ether, sulfoamido.
R2, R3 represent the group of hydrogen atom, alkyl, hydroxyl, aromatic radical etc.R2, R3 can be identical, also can be inequality.
M represents 1-20 natural number, and n represents 1-10 natural number.
By above measure, when coating fluid of the present invention was coated with under the high speed of a motor vehicle, prepared PS version was apparent evenly, do not have grow dim, take off be coated with, apparent disadvantage such as lateral road.
In positive PS printing plate light sensitive coating fluid of the present invention, by weight, wherein 7～10 parts of linear phenolic resins, 2～5 parts of optical light sensitive adhesives, 0.2～0.3 part of dyestuff, 85～90 parts of solvents, 0.1～0.2 part of Compound I.
Specifically, R1 preferably contains the hydrophilic radical of ether in the Compound I, more particularly, and preferably-O-(C
2H
4O)
a(C

6O)
bThe H group, wherein, a, b represent 1～10 natural number.R2, R3 represent hydrogen atom.The consumption of this compound should account for 0.01～1% percentage by weight of total coating fluid, and 0.05%～0.5% is good.
Used one or more lacquer resin among the present invention can be the linear phenolic resin that phenol-formaldehyde resin, metacresol-formaldehyde resin, orthoresol-formaldehyde resin, paracresol-formaldehyde resin, phenol-metacresol-formaldehyde resin, phenol-tertiary butyl phenol-formaldehyde resin, metacresol-paracresol-formaldehyde resin, metacresol-orthoresol-a kind of phenols such as formaldehyde resin, two kinds of phenols even three kinds of phenols and formaldehyde form by the different proportion polycondensation.
Used one or more the optical light sensitive adhesive of the present invention is the diazonium naphthoquinone sulphonate compounds in traditional positive PS printing plate light sensitive component, and its esterification parent can be low molecule polyhydric phenols, also can be macromolecular compounds such as linear phenolic resin.The used optical light sensitive adhesive of the present invention with the diazo naphthoquinone sulfonic acid chloride as graft with the part of hydroxyl esterification of linear phenolic resin and obtain.The synthetic used linear phenolic resin of this family macromolecule resistance solvent can be an above-mentioned film-forming resin phenolics commonly used, and example has phenol-formaldehyde resin, metacresol-formaldehyde resin, orthoresol-formaldehyde resin, paracresol-formaldehyde resin, phenol-metacresol)-linear phenolic resin that formaldehyde resin, phenol-tertiary butyl phenol-formaldehyde resin, metacresol-paracresol-formaldehyde resin, metacresol-orthoresol-a kind of phenols such as formaldehyde resin, two kinds of phenols even three kinds of phenols and formaldehyde form by the different proportion polycondensation.
Used one or more the dyestuff of the present invention can be selected from dyestuffs such as Victoria's ethereal blue, alkaline bright blue, solvent blue, crystal violet, methyl violet, methylene blue.Consider and to reduce the plate sensitivity that preferred Victoria's ethereal blue, alkaline bright blue, solvent blue etc. are comparatively desirable to ultraviolet absorption.
Solvent for use of the present invention can be selected from ethers: ethylene glycol monomethyl ether, ethylene glycol monoemethyl ether, the only ether of propylene glycol, the only methyl ether of propylene glycol etc.; Ester class: ethyl acetate, butyl acetate, glycol methyl ether acetate, ethylene glycol ether acetate, 1-Methoxy-2-propyl acetate, propylene-glycol ethyl ether acetate, isobutyl acetate etc.; Ketone: MEK, methylisobutylketone, butanone, cyclohexanone etc.; Heterocyclic: dioxane, dioxolanes, hexahydro furyl etc.When using single component solvent, should select the solvent that can both dissolve for use to all components.When using mixed solvent, should be main solvent with a kind of solvent, another kind of or two kinds of solvents be cosolvent, and the rate of volatilization between these solvents should be approaching as far as possible.The use amount of main solvent should account for 70～95% percentage by weights of total solvent amount, and 80～90% weight percent are relatively good; The use amount of cosolvent should account for 5～30% percentage by weights of total solvent amount, and 10～20% weight percent are relatively good.
