SOLVENT COMPOSITION FOR OFFSET PRINTING INK, OFFSET PRINTING INK CONTAINING THE SAME, AND PRINTED MATTER

摘要

PROBLEM TO BE SOLVED: To provide a solvent composition for offset printing ink which is a solvent (preferably of plant-derived) used as a substitute for a petroleum solvent contained in an offset printing ink, having drying characteristics and stability on machine comparable to the conventional offset printing ink using a petroleum solvent, hardly swelling a blanket for printing during printing, having less odor, when applied to an offset printing ink, an offset printing ink containing the same, and printed matter using the ink.;SOLUTION: The solvent composition for offset printing ink includes 10-90 mass% of an alkylene oxide adduct having an alkylene oxide added to a 8-18C alcohol, and 10-90 mass% of a dialkyl ether having 8-24 carbon atoms in total. The offset printing ink including the same and printed matter are also disclosed.;COPYRIGHT: (C)2011,JPO&INPIT
