Abstract

The invention discloses a heat-sensitive CTP heat-sensible image-forming liquid with carboxyl phenolic resin active ester and etherate as dissolving inhibitor, belonging to the application technology field of optical information recording material. The image-forming liquid comprises film forming resin, dissolving inhibitor, infrared dye, coloring background dye, photoacid generator, additive and solvent. The dissolving inhibitor is carboxyl phenolic resin active ester and etherate, and the dissolving inhibitor can be decomposed under the action of proton acid generated in the exposed area, to release alkali-soluble groups, e.g. carboxyl or phenolic hydroxyl, thus the dissolving difference between the exposed and unexposed areas is large, and the developing and imaging performance of the plate material is improved. Utilizing the dissolving inhibitor can obtain positive preheating-free heat-sensitive CTP plate material with high sensitivity and good resolution and pressrun.
