Abstract

A pressure-sensitive chromogenic copy system comprising a transfer sheet having on at least a portion of at least one surface thereof a color developer capable of reacting with a chromogen to form a color image, said color developer comprising a crude reaction medium resulting from reactants used to prepare a salicylate and also containing therein at least one metal compound of such salicylate, the resultant transfer sheet, color developer and process for making such color developer.
