Beschreibung
Zusammenfassung:	The invention discloses a high sensitivity positive thermosensitive CTP plate adopting active etherate in condensation resin of pyrogallol and acetone and a preparation method thereof, belonging to the technical field of graphic arts. The plate is composed of a base and an imaging layer. The base is obtained after carrying out cleaning, neutralizing, electrolyzing, oxidizing and hole sealing on the aluminium strips. The imaging layer is an imaging film which is prepared by the steps of dissolving 70-90 parts of film-forming resins, 2-10 parts of inhibitational resins, 2-5 parts of infrared dyes, 2-5 parts of color background dyes, 2-5 parts of photoacid generator and 2-5 parts of additives by weight into 800-900 parts of organic solvent by weight to form coating liquid, coating the coating liquid on the base and drying the coating liquid at 90-140 DEG C for 5-10min. The imaging film is 1.5-1.9g/m2 in thickness. The plate prepared in the invention has the characteristics of high sensitivity, good mesh point re
