INK CONTAINING MICROCAPSULES FOR PRESSURE-SENSITIVE COPYING PAPER

摘要

A microcapsulate ink for use in preparing a pressure-sensitive copying paper comprises Microcapsules A which contain a solution of dyestuff for no-carbon pressure-sensitive copying paper and Microcapsules B which contain a solvent but no said dyestuff and which have been formed in coagulated states, both types of microcapsules being dispersed in a dispersion medium and the mean particle diameter of the said Microcapsules B being from l.l to 3.5 times larger than that of the said Microcapsules A.
