EMULSION INK FOR MIMEOGRAPHIC PRINTING

摘要

PROBLEM TO BE SOLVED: To obtain an ink having excellent emulsion stability and ink dryability, giving high print density and free from bleeding by incorporating an aqueous phase of a W/O-type emulsion with a water-insoluble colorant and a water-soluble polymer containing an acid anhydride. SOLUTION: An ink causing little strike-through phenomenon is produced by incorporating an aqueous phase of a W/O-type emulsion ink containing an oily phase and an aqueous phase with a waterinsoluble colorant and a water- soluble polymer containing an acid anhydride such as an isobutylene-maleic anhydride copolymer or a styrene-maleic anhydride copolymer.
