A fountain solution composition for lithographic printing characterized by comprising at least one acyclic hydrocarbon diol compound, having 9 carbon atoms in total and two —OH groups, wherein the number of carbon atoms existing between said two —OH groups via minimal distance is from 2 to 6, and at least one cationic compound represented by a specific formula.
(In the formulae, R1 and R2, which may be the same or different, each represents hydrogen or lower alkyl.)
The present invention relates to a process for producing 1,5-pentanediol derivatives represented by general formula (II) which comprises reacting 2-butenal derivatives represented by general formula (I) with formaldehyde, and hydrogenating the obtained mixture of reaction products.
