Problems solved by technology

[0003] However, the current common UV-CTP plate can only be used for printing with common offset printing inks. If it is applied to UV ink printing, its surface coating will be dissolved quickly under the action of UV ink, and its life will end after hundreds of printings.

Abstract

The invention relates to a UV-CTP plate imaging coating layer resistant to UV ink. The UV-CTP plate imaging coating layer is characterized by comprising consituents based on percent by mass: 10-60% of solvent resistant resin, 2-12% of solubilizer, 3-25% of dissolution promotion resin, 10-65% of film forming resin, 0-1% of dissolution resistant resin, 6-30% of ester matter of alkylphenol-formaldehyde resin and 2-heavy nitrogen-1-naphthoquinone-4-sulfonyl chloride, 0-30% of ester matter of pyrogallol-acetone resin and 2-heavy nitrogen-1-naphthoquinone-5-sulfonyl chloride, 0-20% of alcohol-resistant dissolution inhibitor and 0.85-2% of dye. With the adoption of the abovementioned technical scheme, the UV-CTP plate imaging coating layer resistant to the UV ink is provided by the invention, is high in UV ink resistance, cannot be dissolved, and has a long printing lifetime.

Description

technical field [0001] The invention relates to an imaging coating for a UV-CTP plate resistant to UV ink. Background technique [0002] UV-CTP plate is a kind of offset printing plate that uses 405nm laser for imaging. Due to its convenient production, moderate cost and convenient use, it has already occupied a considerable proportion in the entire offset printing plate. [0003] However, the current common UV-CTP plate can only be used for printing with common offset printing inks. If it is applied to UV ink printing, its surface coating will be dissolved quickly under the action of UV ink, and its life will end after hundreds of printings. . Due to the increasing application of UV ink printing in packaging printing, the demand for UV-CTP plates with UV ink resistance is becoming more and more urgent. Contents of the invention [0004] Purpose of the present invention: in order to overcome the defective of prior art, the present invention provides a kind of UV-resistan...
