Abstract

PURPOSE:To prevent background staining even with respect to the change in the constitution or preserving and manufacturing condition of a printing plate in an extremely effective manner with good reproducibility and to perform good printing imparting high ink density, by incorporating a specific polymer in a damping liquid composition for a planographic printing plate containing fine inorg. particles. CONSTITUTION:In a damping liquid composition for a planographic printing plate containing fine inorg. particles having an average particle size of 0.1mum or less, a polymer represented by general formula (I) (wherein m and n are mol. numbers necessary for bringing not only the average MW of the block polymer to 600 or more but also m/(m+n) to 50-100wt.%) is contained. By this method, even in ink for an offset rotary press or a plate material easy to generate background staining, the background staining can be prevented in an extremely effective manner and the amount of fine inorg. particles can be reduced and, therefore, a result good in reproducibility is obtained.
