Title: Retouching agent for planographic printing plate
Inventor: MATSUMOTO HIROSHI
IPC: G03F7/00
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To obtain a retouching agent for a planographic printing plate with which only a desired image part can be erased without adversely affecting the adjacent necessary image part by incorporating an org. solvent, a compd. which is dissolved in water to produce fluorine ion, and either of formic acid or oxalic acid. SOLUTION: The retouching agent for a planographic printing plate contains an org. solvent having >=120 deg.C boiling temp., a compd. which is dissolved in water to produce fluorine ion, and at least either of formic acid or oxalic acid. By mixing formic acid or oxalic acid with the compd. which is dissolved in water and produced fluorine ion, local etching in a part of the planographic printing plate to be erased can be suppressed but the mixture has an effect to uniformly etch all over the plate. Therefore, contamination due to corrosion of the plate can be prevented. The retouching agent requires a short time for erasing of an image on the plate so that it gives no influences on a picture part which is not to be erased. Moreover, the agent uniformly etch the grainy surface of the printing plate so that contamination in the erased part is hardly caused.
