<P>PROBLEM TO BE SOLVED: To provide an environmentally friendly pressure-sensitive copying paper solvent and a microcapsule dispersion, and pressure-sensitive copying paper excellent in color developing density and printing conserving properties. <P>SOLUTION: A pressure-sensitive copying paper solvent composition is mainly made of: a fatty acid monoester of an animal oil and of a vegetable oil, and/or a vegetable oil; and a straight chain saturated fatty acid diester represented by general formula: ROOC-(CH<SB>2</SB>)<SB>n</SB>-COOR containing mainly dimethyl glutarate, wherein n is an integer of 2-4 and R is a 1-2C alkyl group. The composition is environmentally friendly, can be employed for a microcapsule dispersion, and then can be employed for manufacturing no-carbon pressure-sensitive copying paper excellent in color developing density and printing conserving properties. <P>COPYRIGHT: (C)2008,JPO&INPIT |
