A protective agent for printed matters obtained by printing with water- based inks. It comprises: one or more solvents comprising at least 50% low-boiling hydrocarbon solvent based on all solvents; and an oleophilic resin soluble therein. The proportion of the low-boiling hydrocarbon solvent to the oleophilic resin is from 97/3 to 40/60 by weight. The low- boiling hydrocarbon solvent has a boiling point of 50 to 110°C. Examples of the low-boiling hydrocarbon solvent include pentane, hexane, heptane, octane, and hexamethylsiloxane. Examples of the oleophilic resin include acrylic ester copolymer resins, silicone-acrylic resins, methyl phenyl silicone resins, and 1,2-polybutadiene elastomers. |
