ABSTRACT:
Desensitization of carbonless copy systems is provided by contacting an electron-accepting, color-reactant material capable of reacting with a substantially colorless chromogenic compound to form a visible image with a desensitizing agent comprising, in combination, a non-volatile, polyoxygenated compound and a strong chelating agent. In this manner, acid-reactive clay coatings typically used in carbonless copy paper systems are effectively desensitized and prevented from reacting with conventional chromogens, such as crystal violet lactone and benzoyl leuco methylene blue.
