Chromogenic derivatives of bis-1,1-disubstituted ethylene and a process for preparing them |
abstract |
A process for preparing a chromogenic compound of normally colorless form is disclosed; - the chromogenic compound having the following structural formula: <IMAGE> R can be, among several others, hydrogen, alkyl, alkoxy, aryl, and heterocyclic, substituted and unsubstituted; and E can be a broad family of aromatic and heterocyclic structures. The compound is eligible for use in pressure-sensitive record materials and manifold marking systems. |
