Abstract
The invention discloses a photosensitive composition with sulfonyl hydrazone-modified phenolic resin as an acid-producing agent, which comprises sulfonyl hydrazone-modified linear phenolic resin, alkali-soluble resin, an infrared absorption dye, and a background dye. The acid-producing agent of sulfonyl hydrazone-modified linear phenolic resin is A-R1=N-NH-SO2-R2. The sulfonyl hydrazone-modified phenolic resin is a key component of the composition of the invention. In an application of positive-printing thermosensitive CTP printing plate materials, sulfonyl hydrazone-modified phenolic resin in a scanning area is subjected to chemical reaction under a heating condition, is decomposed to release alkali-soluble groups, such as a phenolic hydroxyl group or a sulfo group, and is further decomposed to generate nitrogen, so as to have foaming and dissolution promotion effects; a non-scanning area has dissolution inhibition effect; therefore, a great dissolution difference between the scanning area and the non-scanning area is formed.
Description
Technical field
The present invention relates to a kind of technical field of photosensitive composition.Specifically the present invention relates to a kind of modified using sulphonyl hydrazone
Application of the phenolic resin as the photosensitive composition of acid agent and its in positive-printing heat-sensitive CTP plate material.
Background technology
Be applied to after offset printing from the PS versions sixties in 20th century, offset plate making technique continue to use always photo-sensation egative film, layout,
Technique before the print that printing down, PS versions are developed and printed.But the shortcoming of this plate-making mode also gradually comes out, this kind of plate-making mode flow process
Long, site loss is big, printing quality is less high, and particularly environmental pollution is larger, in order to change this situation, 80 years 20th century
Generation, the U.S., Japanese some companies start to develop CTP (Computer to plate, abbreviation CTP) skill
Art, current CTP technologies are developed rapidly, and in the popularization and application stage.CTP technologies are divided into photosensitive CTP plate-making technologies and heat
Quick CTP plate-making technologies, wherein positive heat-sensitive CTP plate-making technology are current most ripe, most stable, the best plate-making technologies of effect.
This technology mainly utilizes photothermal conversion principle, i.e., when iraser (830nm) carries out image scanning on plate to expose, sweep
Retouch part infrared absorbing dye absorbing light and be converted into heat energy, cause scanned regional temperature to be increased to more than threshold temperature, cause
Acid is produced in light thermal acid generator thermal decomposition in plate, and under the action of an acid, the heat susceptible coating for seeing light region is decomposed reaction, with alkali
Dissolubility, is dissolved during development treatment, exposes the blank parts that hydrophilic version base becomes hydrophilic；Have no the heat susceptible coating in light region
Do not decompose reaction, not with alkali solubility, the space of a whole page is still remained in after development treatment becomes the areas of oleophylic.Wherein version
The acid agent used in material is the key component that coating occurs hydrophilic change, and this material can be produced by the thermally-induced product acid source of light
Raw proton or free radical, produced acid makes resin decompose under conditions of room temperature or heating, so that illumination coating is sent out
Life chemical reaction soluble in water.
Light thermal acid generator main species have diazols compound, salt, organic polyhalogen compound, sulphonic acid ester and triazines
Compound etc., these acid agents in use, due to different to light source energy absorption, made by one section of storage having of plate
Occur sensitivity after time and decline fast, stability is bad, and phenomenon of keeping on file after some developments, some solvent resistances are poor, also resistance to
Print rate is not high, so so far the using effect of this acid agent is not good.For these problems, each company is to temperature-sensitive acid agent
Use and substantial amounts of research work has been done in selection, specifically, temperature-sensitive digitized has been invented by the 1980s, Kodak
Direct plate-making technology (US5340699, US5491046, US5466557), this plate phenolic resin is used as film-forming resin
Hydroxymethyl resins make cross-linking agent, with iodine salt or compound in triazine class as light thermal acid generator.Before this technology is using development
Preheating procedure, relatively costly, operation is also long.Journal of the Organic Chemistry, 43 (15) (1978) reports
Triphenyl sulfosalt derivant is led.JP7-28237 has reported alkyl sulfide salt derivative, and for example (2- is oxo for cyclohexyl methyl
Cyclohexyl) sulfosalt trifluoromethyl sulfonic acid.Journal of th Polymer Science, 56 (1975) have reported hexichol
Base iodine salt and succinimide derivatives.Plate obtained in these acid agents, phenomenon of keeping on file after some developments, what is had is anti-molten
Agent is poor.Double trichloromethyl-the 1- of 3,5- used by (Unexamined Patent -11-119428,11-24248) are to first in Mitsubishi Chemical Ind's patent
The routine acid agent such as diphenyl iodnium used by oxygen styryl triazines chemical combination and Kodak, it is solid in image forming composition
Body gross mass accounts for 1-10% weight, but only can only obtain the negative image of preheating with the acid agent that these thermal CTP plate materials are general
Hot glue connection type heat-sensitive CTP plate, is difficult to obtain the thermal CTP plate material of positive image or negative image without preheating.CN1380180A discloses one kind
The direct method for platemaking of coating type negative thermo-sensitive computer, wherein in heat sensing layer thermal acid generator be with used by Kodak,
It is the diphenyl iodnium with hexafluoro-phosphate radical as anion, what is obtained is negative engraving.
The present invention relates to class sulphonyl hydrazone Modified Phenolic Resin compound, its solvent resistance is good, and is preparing
Dissolubility is good in liquid, good stability, and other photoactive components have and mix well effect, release under photothermy sour efficiency high and
Hurry up.
