PURPOSE:To obtain a correction liquid of an original plate film for photographic platemaking, such as making a presensitized plate, freed of gellation at low temperatures, and peeling of corrected parts, by using chloroprene type or the like synthetic rubber as a resin component. CONSTITUTION:A chloroprene or the like type synthetic rubber, or a synthetic resin having tackiness and flexibility, solvent, carbon black, and when needed, anhydrous silica are mixed and used as a correction liquid of an original plate film for photographic platemaking, such as making a presensitized plate, thus permitting use of benzene high in toxicity as a solvent to be unnecessary, the correction liquid not to gel at low temperatures, the corrected parts not to peel, and the corrected original plate film to be stored for a long term without deterioration. |
