Abstract

The invention discloses thermosensitive CTP thermal-induction imaging liquid taking an active etherate of a pyrogallol and divinylbenzene polycondensate resin as a dissolution inhibitor, belonging to the applied technology field of an optical information recording material. The imaging liquid comprises the following components: film-forming resin, dissolution inhibitor, infrared dye, coloring background dye, photoacid generator, an additive and solvent. The dissolution inhibitor is the active etherate of the pyrogallol and divinylbenzene polycondensate resin, and the dissolution inhibitor can decompose and release an alkali soluble group, namely phenolic hydroxyl under action of protonic acid generated in an exposed area so as to form great dissolution difference between the exposed area and a non-exposed area, thus enhancing developing and imaging performances of a plate. The dissolution inhibitor can obviously enhance sensitivity and ageing resistance of the thermosensitive CTP plate, improve development latitude of the thermosensitive CTP plate, and strengthen comprehensive imaging performance of the thermosensitive CTP plate.
