Abstract
The invention discloses a sensitizing composition and a lithograph plate using the sensitizing composition. The sensitizing composition comprises the following components by weight portion according to solid amount of the composition: 30 to 60 portions of alkali resin, 5 to 20 portions of infrared absorption compound, 5 to 20 portions of photo-thermal generating-acid source, 5 to 15 portions of acidolysis dissolution resistant compound, and 5 to 15 portions of physically changed dissolution resistant compound. The lithograph plate comprises a base, the base is provided with a bottom coating containing hydrophilic polymers, and a light-sensitive coating of the sensitizing composition is adhered to the bottom coating. Because the sensitizing composition and the lithograph plate adopt the components, by testing a plurality of printing plates, the image printing number of the printing plate reaches 100,000; if the lithograph plate is roasted at a temperature of 220 DEG C for 10 minutes, the printing number can reach 300,000; moreover, the lithograph plate also has the advantages of high sensitivity and large development latitude.
Description
Technical field
The technical field of the invention is the image-forming information recording materials, the plate making technical field that promptly has high sensitivity, be specifically related to the photosensitive composition that a kind of positive-printing heat-sensitive CTP plate material is used, also relate to the planographic printing plate material of the photosensitive composition making of using with positive-printing heat-sensitive CTP plate material.
Background technology:
The huge change that the CTP technology brings for press, the people in the industry is obvious to all already, is accepted by increasing printing enterprise and approves.With regard to the CTP Developing Trend in Technology, the thermosensitive CTP plate-making technology is day by day ripe and universal, and the novel thermosensitive CTP plate of exploitation function admirable becomes one of focus of plate material manufacturing enterprise concern.Commercial at present thermal CTP plate material has several.
A kind of is negative heat cross-linking type thermal CTP plate material, contains linear phenolic resin and resol resin in the thermographic composite formula of this plate, and infrared absorbing compounds and photo-thermal produce the acid source compound.Plate produces acid under infrared laser scanning, acid plays catalytic action and makes resin crosslinks in the heating process of plate, removes not scan exposure part then in alkaline-based developer, forms the negative forme, and it is necessary controlling heating-up temperature accurately.And there are problems such as complex process, plate sensitivity be low.
Another kind of heat-sensitive positive picture CTP plate material has removed the preceding preheating treatment procedure of development in the negative heat cross-linking type thermal CTP plate material.The main component of filling a prescription in this plate imaging layer is the film forming phenol resin, compound is dissolved in the resistance of infrared absorbing compounds and non-photosensitivity, the carbonyl of compound is dissolved in resistance before the exposure, phenolic hydroxyl group in hydroxyl or amino etc. and the film-forming resin forms the hydrogen bond between the molecule, make the thermographic composition that the molten effect of resistance be arranged before exposure, and infrared laser when scanning, because infrared absorbing compounds can be converted into heat energy with luminous energy, the hydrogen bond of thermographic composition is destroyed, make the phenolic hydroxyl group of phenol resin be released, thereby cause the exposed portion alkali solubility to strengthen, processing through alkaline aqueous solution can be removed exposed portion, obtains the positive forme.The pre-heat treatment before this thermal CTP plate material does not need to develop, but the alkali dissolubility difference of this plate exposed portion and non-exposed portion is little, the development tolerance is little, and sensitivity is low, and practical operation is strict.
Also have a kind of heat-sensitive positive picture CTP plate material, utilize chemically amplified photo resist agent technology, compositions such as compound, infrared absorbing compounds, product acid source compound are dissolved in the resistance that its thermosensitive imaging composition contains film-forming resin, acidolysis.The image-forming principle of the image forming composition of this type of plate is a chemical change, resistance solvent decomposes alkali-soluble groups such as producing phenolic hydroxyl group, carboxyl under the action of protonic that exposure region produces, make exposure region and non-exposed area produce the dissolubility difference, thereby obtain positive images, The pre-heat treatment before not needing to develop, but the alkali dissolubility before and after the film-forming resin exposure does not have variation substantially, therefore, this kind plate is kept on file seriously, goes up dirty.
The present invention originally provides a kind of photosensitive composition of positive heat-sensitive CTP brush version and has used the plate of its making, utilized the method for short molten principle of thermic and the combination of chemically amplified photo resist agent technology, use special alkali solubility compound, a kind ofly use a kind of high activity acid decomposition of chemical compounds (auspiciously to see the Chinese patent application application number: 200310110104.X), resistance solvent, acid agent, infrared absorbing agents and the molten phenol resin of acidolysis alkali is arranged, obtained the positive-printing heat-sensitive CTP plate material that is used for infrared laser of higher sensitivity, bigger development tolerance by synthetic.
