Gordian technique of the present invention be this novel photo-thermal produce the design of acid source, synthetic with and application in photosensitive composition.Certainly, light used in Mitsubishi Chemical Ind's patent produces acid source 3, and the two trichloromethyl-1-of 5-replace described photo-thermal to produce acid source to the light product acid source that the used conventional light product acid sources such as diphenyl iodine salt of methoxy styryl compound in triazine class and Kodak all can be used as in the image forming composition of the present invention undoubtedly with part.The amount ranges that these conventional light produce acid source generally accounts for 1-10% weight in image forming composition solid gross mass.But, only produce acid source with the general light of these thermal CTP plate materials, can only obtain the negative heat cross-linking type heat-sensitive CTP plate of preheating, be difficult to obtain positive or negative without preheating thermal CTP plate material.Innovation part of the present invention is: at first, and based on 2,1, the 4-diazonium naphthoquinone sulphonate is after UV-irradiation, and the diazo naphthoquinone base decomposes, isomerization, become indenes acid structure after, the ester group of sulphonic acid ester also is easy to decompose and produces sulfonic acid, and this is the work reported of someone in the past.We are valuable imagination: the sulphonic acid ester that becomes indenes acid structure should be under the effect of heat, and than 2,1, the easier decomposition of 5-diazonium naphthoquinone sulphonate produces sulfonic acid.The second, we affirm that this photo-thermal produces acid source, and a process by resistance solvent change chaotropic agent can take place, and has very large dissolving contrast in developer solution, thereby is very beneficial for forming positive without preheating thermal CTP plate material before and after the effect of light and heat.The 3rd, we have used for reference structures such as phthalimide, naphthalimide and have been easy to phenolics the insoluble process of certain buck take place under the effect of heat, and this structure is imported in the sulphonic acid ester, constitute the composite crosslinking curing system with hexamethoxymethyl melamine.Thereby this sulphonic acid ester had both been done the product acid source, done the molten/chaotropic agent of resistance again, doublely done auxiliary crosslinking and curing agent, successfully obtained negative without preheating heat cross-linking type thermal CTP plate material.At last, we find that also corresponding p-toluenesulfonic esters also has similar performance.
Above-mentioned novel product acid source compound can be by comprising 2,1,4-diazo naphthoquinone sulfonic acid chloride or paratoluensulfonyl chloride and be selected from the esterification of linear phenolic resin that N-hydroxyl acid imide material, polyhydroxy phenol compounds and weight-average molecular weight are 2000-4000 or the method preparation of reaction of grafting parent and separating obtained product.
2,1, in 4-diazonium naphthoquinone sulphonate or the p-toluenesulfonic esters class material there be much required esterification parent, as mentioned above, the esterification parent that the present invention uses has three classes: 1. N-hydroxyl acid imide material, and as N-hydroxyphthalimide, N-hydroxyl naphthalimide, N-hydroxy tetrahydro phthalimide, N-hydroxyl norborene dicarboximide, N-maloyl imines etc.Consider from aspects such as its solvent nature, reaction complexity and imaging characteristics, recommend to use the N-hydroxyphthalimide.2. the polyhydroxy phenol compounds that obtains by resorcinol condensation or addition, as addition product, resorcinol and the tung oil of condensation product, resorcinol and the rosin of condensation product, resorcinol and the benzil acid of condensation product, resorcinol and the cyclohexanone of resorcinol and acetone or eleostearic acid and with addition product of laccol etc.These polyhydroxy phenol analog derivatives are with 2,1, need not be as the first kind material when 4-diazo naphthoquinone sulfonic acid chloride or paratoluensulfonyl chloride esterification 100% esterification, only need 〉=50% phenolic hydroxyl group esterification is got final product.3. weight-average molecular weight is the linear phenolic resin of 2000-4000, metacresol-formaldehyde resin for example, orthoresol-formaldehyde resin, phenol-metacresol-formaldehyde resin, phenol-paracresol-formaldehyde resin etc., the phenolic hydroxyl group esterification yield in these matrix resins gets final product between 20-50%.From the solvent nature and the imaging performance of the carboxylate that synthesized, preferably use condensation product and some low-molecular-weight linear phenol-aldehyde resin of N-hydroxyphthalimide, resorcinol and acetone or cyclohexanone.By above first to the three class esterification parent and 2,1,4-diazo naphthoquinone sulfonic acid chloride or paratoluensulfonyl chloride reaction photo-thermal synthetic of the present invention produces the Chinese patent application 03156178.0 that the program of acid source can the REFERENCE TO RELATED people be submitted on September 3rd, 2003, and whole disclosures of this application are hereby incorporated by reference.For example, can make above-mentioned first to the three class esterification parent and 2,1,4-diazo naphthoquinone sulfonic acid chloride or paratoluensulfonyl chloride are in being selected from acetone, dioxane, DMF in one or more the solvent, utilize and 2,1, mole such as 4-diazo naphthoquinone sulfonic acid chloride or paratoluensulfonyl chloride or slightly excessive triethylamine are as neutralization reagent or catalyzer, between 0-40 ℃, drip catalyzer, Synthetic 2 thus, 1,4-diazonium naphthoquinone sulphonate or p-toluenesulfonic esters, the esterifying reagent molal quantity is the 50-100% of phenolic hydroxyl group total mole number in the grafting parent.Isolation and purification method is that reactant liquor is injected distilled water more than 10 times, and the evolution reaction product filters, and washes with water repeatedly, between 45-50 ℃ with the product drying.What should emphatically point out is, Synthetic 2, and 1, during 4-diazo naphthoquinone sulphonyl oxygen phthalimide, the double solvents that must use DMF or contain DMF reacts.Shown in the general formula 12,1,2 shown in 4-diazo naphthoquinone sulphonyl oxygen phthalimide (PAG-1), the general formula 2,1, shown in 4-diazonium naphthoquinone sulphonate (PAG-2) and the general formula 32,1,4-diazonium naphthoquinone sulphonate (PAG-3) are that three kinds of recommending to use of the present invention produce acid sources.

Wherein R is
In image forming composition of the present invention, the total content that above-mentioned photo-thermal produces acid source and the optional conventional light product acid source that uses is 1-20% weight based on the composition solid gross mass, preferred 2-10% weight.
Film-forming resin in the image forming composition of the present invention is generally selected line style phenol resin, for example weight-average molecular weight for use
Be the poly(4-hydroxystyrene) of 5000-20000, poly-o-hydroxy ethene or their modified product.Also has weight-average molecular weight
Be 3000-8000,
Phenol-formaldehyde resin between 3-10, metacresol-formaldehyde resin, orthoresol-formaldehyde resin, phenol-metacresol-formaldehyde resin, phenol-orthoresol-formaldehyde resin, phenol-paracresol-formaldehyde resin, phenol-tert-butyl group resinox, phenol-metacresol-paracresol-formaldehyde resin, metacresol-paracresol-formaldehyde resin and metacresol-tert-butyl group resinox etc.Their content in the imaging constituent is generally the 50-90% weight of composition solid gross mass, is preferably 60-80% weight.If consumption is too big, then a little less than the molten ability of the resistance of image forming composition, poor to the resistivity of alkaline developer, membrane left rate is low in the developing process, not only influences picture resolution and dot reproduction, also can reduce the press resistance rate of the forme that is coated with.Otherwise, consumption very little, crosslinking chemical and other consumptions that hinder molten component must increase, though sensitivity might improve (to negative engraving), its development capability descends, be easy to produce keep on file, residual dirty phenomenon, also can reduce the resolution and the dot reproduction of image.For positive without preheating CTP plate, film forming line style phenol resin is preferably in the main chain or contains a certain amount of acid-decomposed activity ehter bond on the side chain.For the negative heat-sensitive CTP plate, should select the bigger line style phenol resin of alkali solubility height and molecular weight for use.
Crosslinking chemical in the image forming composition of the present invention can have a variety of selections, for example can use methylolation linear phenol-aldehyde resin, methylolation poly(4-hydroxystyrene), methylolation polyphenolic substance.Also can be methylolation melamine, methoxymethylation line style phenol resin, methoxymethylation poly(4-hydroxystyrene), methoxymethylation polyphenolic substance, methoxymethylation melamine etc.Because the polarity of methylolation phenol resin or polyphenolic substance, methylolation melamine is stronger, and is relatively poor to the molten ability of the resistance of alkaline solution, and their thermal stabilitys in image forming composition are not so good; In addition, methoxymethylation phenol resin and polyphenolic substance, the activity that cross-linking reaction takes place under the acid effect is lower, the image taking speed deficiency, so the present invention recommends the hexamethoxymethyl melamine that uses the methoxylation ratio high as far as possible, the etherificate rate of its methoxylation is preferably in about 95%.
The consumption of crosslinking chemical in image forming composition should account for the 1-20% weight of composition solid gross mass, is preferably 5-15% weight.As the image forming composition of positive without preheating heat-sensitive CTP plate, the consumption of crosslinking chemical should be below 5%, and as negative heat cross-linking type heat-sensitive CTP plate image forming composition, dosage of crosslinking agent should be at 5-15%.Consumption is too big, and residual dirty phenomenon easily takes place the difficulty of developing, and influences forme resolution.Consumption very little, the crosslinking curing deficiency not only reduces sensitivity, and influences the press resistance rate of forme.
The synthetic method of the hexamethoxymethyl melamine of the high etherificate rate of using among the present invention can be with reference to the synthetic method of many alkoxymethyl melamines in the traditional paint coating amino resins.Here only need to strengthen the consumption of methyl alcohol, so that obtain the etherificate rate at the hexamethoxymethyl melamine more than 90%.
Photo-thermal conversion material in the image forming composition of the present invention is infrared absorbing dye commonly used, and it can be that used benzindole is cyanine dyes, step cyanine dye and various λ in the traditional thermal CTP plate
