ABSTRACT:
New fluoran compounds containing a dibenzylamino group or a nuclear substituted derivative thereof are provided by a novel method involving the reaction of an aminofluoran and a benzyl chloride in the presence of alkali in an inert non-polar organic solvent. The dibenzylamino fluorans are incorporated as a remarkably effective color former in pressure sensitive copying paper.
