MICROCAPSULES OF PRESSURE-SENSITIVE COPYING PAPER

摘要

A dye solvent useful as a material for microcapsules necessary for the manufacture of pressuresensitive manifold paper. This solvent essentially consists of a hydroaromatic compound for pressuresensitive manifold paper. The compound is a polycyclic aromatic compound with three or more aromatic rings, some of which rings have been hydrogenated and exhibits solvency, particularly, for a black pigment and a blue pigment of leuco dye.
