To give good penetrability in cleaning a metal mask plate and realize improvements in continuous printability, detergency, etc., by blending a fluorine compound with solvents comprising, e.g. a hydrocarbon and an alcohol.
This improver is obtained by blending 0.15-45wt.% fluorine compound comprising an oligocopolymer of a 4-20C polyfluoroalkylated unsaturated ester, such as CF3(CF2)4CH2OCOC(CH3)=CH2, and other copolymerizable compound with at least one solvent selected from hydrocarbon solvents such as isoparaffin and n-hexane, alcohols such as isopropyl alcohol and ethanol, chlorine compound solvents such as methylene chloride and trichloroethylene, hydrochlorofluorocarbons such as HCFC-225, fluorocarbon solvents, water-soluble solvents, glycol ether solvents or ester solvents. It is used by spraying to prevent it from being contaminated with contaminants falling from a metal mask plate.
