Dampening water composition for lithographic printing plate

A dampening water composition for a lithographic printing plate comprising polyvinylpyrrolidone and at least one compound selected from the group consisting of acetylene alcohol, acetylene glycol, n-butyl alcohol, isobutyl alcohol, secondary-butyl alcohol, tertiary-butyl alcohol, a compound of (CH 3 ) 3 C—O—(—CH 2 —CH 2 —O—) p —H wherein p represents an integer of from 1 to 3, 3-methoxy-3-methylbutanol, 3-methoxybutanol, a compound represented by the following formula (I) and a compound represented by the following formula (II). 1 (wherein R represents n-butyl, isobutyl, tertiary-butyl or secondary-butyl group, and n represents an integer of 1 or 2.) 2 (wherein m represents an integer of from 1 to 3.) Said dampening water composition is comfortable and safe in working atmosphere and is excellent in printing stability, which can replace a dampening water composition comprising isopropyl alcohol. Said dampening water also exhibits favorable and stable printing properties under the conditions of printing machine members which rotate at high speed, and stable printing properties to various ink compositions so as to obtain excellent printing matters.
