Concentrated dampening water composition for lithographic printing

摘要

A concentrated dampening water composition comprising an organic solvent having a solubility of 1 to 10% in water at 20 DEG C, which composition comprises at least one selected from the group consisting of maleic acid and a salt thereof. The concentrated dampening water composition is stably solubirized, in spite of the existence of an organic solvent having a low water-solubility therein, and said composition does not have problems of foaming and deterioration of printing properties.
