Description

Radiation sensitive composition
Technical field
The present invention relates to a kind of radiation sensitive composition that is used for lithographic plate.
Background technology
Lithographic characteristic is that the image area (image area) of inking on the lithographic plate and the non-image district of not inking exist together in one plane.Wherein, image area is an oleophilic drainage, and non-image district then is hydrophilic oleophobic.Lithographic mode of operation; Promptly be to utilize oil (oily matter or printing ink (ink)) and the immiscible characteristic of water, water for earlier forme, make non-image district form the moisture film of hydrophilic oleophobic; And then to the forme inking; Make image area partly attach printing ink, under the effect of squeegee pressure, the picture and text on the forme are transferred to paper or other stock surface through blanket cylinder.Usually printing ink is transferred to the blanket (blanket) that is commonly referred to as intermediate materials, then, again printing ink is transferred to the material surface of treating duplicating image, promptly like surfaces such as paper, cloth, plastics or metals.
Precoating formula sensing optical activity lithographic plate (Pre-Sensitized Plate; The PS version) manufacturing approach; Roughly be surface process electrolysis or grinding earlier with an aluminium sheet; To form the Grains that a plurality of printshops need, again the radiation sensitive composition of sensing optical activity or thermonasty is coated on the Grains of this aluminium sheet forming a radiation-sensitive coating, and this radiation-sensitive coating is toasted slaking.Then, see through one have predetermined image and literal egative film, the image on this egative film and the literal mode with exposure and develop (develop) is transferred on the radiation-sensitive coating, to process in order to image and the galley of text printout on file.
In recent years, use a computer and handle and the digitizing technique widespread use of image output information, the new image way of output of various correspondences is practicability.On lithography, if can omit the making of egative film, directly with the digital pattern of computing machine via the exposure imaging program, be transferred on the radiation-sensitive coating; To process in order to image and the galley of text printout on file; The plate-making operation is greatly simplified, can significantly be increased printing speed and reducing cost, this kind technology is called CTP (Computer To Plate; CTP), obtain and how being applicable to that this technological galley becomes important problem.
After being coated on the radiation sensitive composition exposure on the employed surface of aluminum plate of lithography, its exposed portion changes alkali-soluble into, thereby at developing process it is removed.This kind version is called the positive type light sensitive version; Otherwise exposed part can harden (curing), changes the alkali insolubility into, then is called the negative photosensitive version.When above-mentioned two situations, residual image area is absorbency or lipophilicity, but not image area is water absorptivity or water wettability.The eurymeric of light sensitive plate or minus depend on the radiation sensitive composition that surface of aluminum plate is coated with.
Above-mentioned radiation sensitive composition mainly is made up of following different materials: radiation absorbability dyestuff (emulsion or sensible heat agent), acid forming agent, phenolics (film forming agent), copolymerization macromolecule, solvent, and other auxiliary agent.
Prior art; For example United States Patent (USP) the 6th; Disclose a kind of positive type light sensitive version that is coated with the potpourri of phenolics (novolac) or cresol-formaldehyde resin (cresol-formaldehyde) or polyhydroxystyrene resin (poly (hydroxystyrene)) and infrared ray absorbing dyestuff for 063, No. 544.In addition, United States Patent (USP) the 5th, 372,907,5; 372,915,5,340,699,5; 491, No. 046, then be coated with the potpourri of novolac type phenolics, cresol type phenolics, infrared ray absorbing dyestuff or pigment and potentiality Bronsted acid (Latent Bronsted acid).When these versions were exposed to infrared radiation, the potentiality Bronsted acid decomposed a kind of different kenel phenolics (for example novolac and cresol) that impel of generation crosslinked material takes place, and makes the mixture cures in the exposure region.Further during the galley of this exposure of heating, filming of this exposure hardened more and it is become be insoluble in the alkaline-based developer, promptly still be not dissolvable in water in the liquid developer solution yet there is exposed areas.United States Patent (USP) the 5th; 919; Disclose the radiation sensitive composition of forming by resin glue (binderresin), crosslinking chemical, thermal excitation acid forming agent (thermal-activated acid generator) and infrared absorbent No. 601; After this constituent was exposed to infrared ray, this acid forming agent promptly divided and explains acid, and then causes the cross-linking reaction that resin glue is carried out through crosslinking chemical by this acid.
The common shortcoming of above-mentioned each technology, be exactly after the galley video picture its image area that manifests often be short of integrality (integrity), can't supply long-time effectively printing, so that the sharpness and the printing quality inequality of the printed images that produces.
Yet; Constantly be asked to improve plate-making efficient and printing quality the printer; Under the prerequisite that promotes industrial competitiveness, the sensitivity of the radiation-sensitive coating on the galley is asked to must be faster, and promptly its required energy that makes public time lower or that its exposure is required is shorter.And exposed portion needs to be developed liquid more easily and washes off when developing, the immersion that unexposed portion then needs more anti-developer solution with wash away, also promptly when developing the temperature of developer solution, concentration, and to soak the tolerance of the conditions such as time of washing away bigger.Simultaneously, also must be able to keep fine resolution, inking property, and the abrasion performance of the radiation-sensitive coating of completion.In addition, the then property of radiation-sensitive coating and aluminium sheet also needs better.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of radiation sensitive composition; Its employed radiation sensitive composition; Do not influencing under exposure sensitivity and the development tolerance, can effectively improve hardness, abrasion performance, stickability and the anti-seal amount of radiation-sensitive coating.
