Abstract

The invention discloses an application of active etherate containing pyrogallol acetonide resin as heat-sensitive CTP thermo-sensitive imaging liquid of dissolution inhibitor, relating to the technical field of optical information recording material application. The imaging liquid comprises the following components: film-forming resin, dissolution inhibitor, infrared dye, coloring background dye, acid-forming agent, additive and solvent. The dissolution inhibitor is the active etherate of the pyrogallol acetonide resin, which decomposes and releases an alkaline solubility group-phenolic hydroxyl under the action of protonic acid produced in an exposure area, thereby creating a large dissolution difference between the exposure area and a non-exposed area, and increasing the developing and imaging performances of plates. The dissolution inhibitor can obviously increase sensitivity and aging resistance, development latitude and comprehensive imaging performance of the heat-sensitive CTP plate.
