Abstract (en)
[origin: EP0397407A2] A finisher composition for lithographic printing plates comprises a water-soluble resin having a film-forming ability and a compound selected from an acetylene alcohol, an acetylene glycol and an adduct of an alkylene oxide with the acetylene alcohol or acetylene glycol. When used for gumming-up, the finisher composition provides a strong effect of desensitizing the non-image areas of the lithographic printing plates. It does not affect or lower the ink receptivity of the image areas of the lithographic printing plates, and has a high throughput capacity.
