Abstract
Abstract WHEREIN R is hydroxyl, amino, amino substituted by at least one lower alkyl group having 1 to 5 carbon atoms, nitro or chlorine, which is substituted on one of the carbon atoms at the side adjacent to that of the carboxylic group on the aromatic ring, each X is a substituted or unsubstituted group containing a monocyclic or bicyclic carbon ring formed with 6 or 10 carbon atoms, m is an integer of 1 to 2 and n is an integer of 1 to 3. The sheet of record material is sensitized with an improved coating to produce color on contact with lactone chromogenic compounds. The coating comprising a binder and a color reactant material. The color reactant material essentially comprises in combination: A. A metal ion of a metal selected from the group consisting of zinc, aluminum, calcium, magnesium, titanium, nickel, cobalt, manganese, iron, tin, chromium, copper and vanadium, or a water insoluble inorganic compound of a metal selected from said metal group, and B. An aromatic carboxylic acid derivative including as its major functional arrangement the molecular structure represented by any of the following formulae:
