Abstract
A kind of laser printer direct imaging offset printign plate material, be by support, image fixed bed and image receiving layer are formed, the image fixed bed is the high molecular weight hydrophilic compound that contains hardener, image receiving layer also has lipophile polymer substance and other auxiliary agents for containing inorganic pigment fine particle and sensitizing, desensitization material.The pressrun of plate of the present invention can reach 2000～5000 seals.
Description
The present invention relates to the plate that a kind of light printing is used, particularly a kind of direct imaging offset plate material that is used for laser printer.
Development along with light printing technology, the kind of light printing plate is also more and more, as on support, scribbling the electrofax type forme of photoconductive layer, on support, scribble the silver halide photography type forme of silver halide emulsion layer, these plates in use technology are loaded down with trivial details, the plate-making of need taking pictures, therefore, developed a kind of direct imaging version in recent years again, this plate need not taken pictures, and directly exports forme by laser printer or printer, also can make a plate with xerography, the plate-making process is simple and direct, rapidly, these products such as Japan Patent JP-A-60181457, and JP-A-61148097 is disclosed like that, by support, the image fixed bed, image receiving layer is formed.But remain in the not enough such defective of pressrun according to the product that these prior arts are produced.
Purpose of the present invention is exactly in order to overcome the above-mentioned defective of existing plate, to provide a kind of plate-making process easy, rapid, the laser printer direct imaging offset printign plate material that has higher pressrun again simultaneously.
The objective of the invention is to be achieved by following means: laser printer direct imaging offset printign plate material according to the present invention is to scribble image fixed bed and image receiving layer on the support of bottom successively having, the image fixed bed is the high molecular weight hydrophilic compound that contains hardener, image receiving layer contains inorganic pigment fine particle and sensitizing, desensitization material, also has lipophile polymer substance and other auxiliary agents.
Select the material the same for use according to the support of laser printer direct imaging offset printign plate material of the present invention, as through the dacron chip base of paper, film, synthetic paper, tectorial paper such as the one-side band bottom of water-fast processing, three vinegar sheet bases of one-side band bottom etc. with prior art; Barrier coating on support at first makes the original not hydrophilic sheet base can be bonding well with hydrophilic image fixed bed, also can select the support that itself has bottom for use.The image fixed bed is selected borax, gelatin, 2 for use, 4-two chloro-6-equal three
Succinate sodium 2-ethylhexyl and water or borax, gelatin and water; Image receiving layer is selected for use: titanium dioxide, zinc oxide, alundum (Al, polyvinyl alcohol, polyvinyl butyral resin, m-cresol resin, ammonium chloride, succinate sodium 2-ethylhexyl, second alcohol and water or titanium dioxide, zinc oxide, polyvinyl alcohol, polyvinyl butyral resin, m-cresol resin, ammonium chloride, succinate sodium 2-ethylhexyl, second alcohol and water or titanium dioxide, zinc oxide, alundum (Al, polyvinyl alcohol, m-cresol resin, ammonium chloride, succinate sodium 2-ethylhexyl, the second alcohol and water.
The manufacture craft of plate of the present invention is, is coated with the epigraph fixed bed with coating process as using the dip-coating coating machine on support, and coating weight is 30～70g/m
2, to use with quadrat method again and coat image receiving layer, coating weight is 120～140g/m
2Carry out drying at last, baking temperature is between 80-120 ℃; Just carry out drying easily if in coating, add some alcohol.
Below in conjunction with drawings and Examples the present invention is described in further detail.
