preparation example Construction

[0065] The second aspect of the present invention provides a preparation method of UV-CTP photosensitive glue, which includes the following steps: adding the above components into the solvent in sequence according to the formula, stirring for 10-20 hours, and filtering after complete dissolution to obtain the photosensitive glue.

[0066] In the present invention, the solvent can be selected from one of methyl ethyl ketone, butyrolactone, ethylene glycol ethyl ether, ethylene glycol monoethyl ether, ethylene glycol monomethyl ether, butyl acetate, dioxane, tetrahydrofuran, butanone one or more combinations.

[0067] Preferably, the solvent is a mixed solvent of butyrolactone, ethylene glycol ether, butanone, and dioxane.

[0068] As more preferably, the volume ratio of butyrolactone, ethylene glycol ethyl ether and butanone in the mixed solvent is (0-10%):(20%-90%):(0-60%).

[0069] As most preferably, the volume ratio of butyrolactone, ethylene glycol ethyl ether and butanon...

Abstract

The invention relates to the technical field of photosensitive adhesives, and in particular relates to a UV-CTP photosensitive adhesive and a preparation method thereof. The UV-CTP photosensitive adhesive comprises, by mass, at least 0.1 to 4% of coloring dye, 5 to 40% of photosensitizer, 30 to 60% of film-forming resin, 5 to 40% of alcohol-resistant resin, 0.1 to 5% of anti-solvent, and 1 to 8% of monofunctional acid anhydride. The photosensitive adhesive has the advantages of excellent alcohol resistance and high print resistance, and can reach 200,000 prints. At the same time, the photosensitive adhesive prepared by the invention has large latitude, is suitable for 1: 2 to 1: 7 dilution of the Huaguang PD-type positive picture PS version developing solution, and can be used for both strong development and weak development. At present, many photosensitive adhesives on the market can only adapt to strong development or only weak development, and the development latitude is very limited.

Description

technical field [0001] The invention relates to the technical field of photosensitive glue, in particular to a UV-CTP photosensitive glue and a preparation and testing method thereof. [0002] technical background [0003] The digitalization of printing plate making is the general trend of the printing plate making industry at present, thus giving birth to a large number of new technologies of computer-to-plate making. UV-CTP system technology is one of them. Computer to Plate (CTP for short) refers to the process of directly outputting graphics and text to the printing plate through the computer, mainly refers to the off-line direct plate making process. CTP technology converts digital pages directly into printing plates, eliminating the need for traditional prepress procedures and corresponding equipment such as laser phototypesetting photosensitive film or electronic color separation film imposition, printing, and PS plate washing. It not only simplifies the production p...
