ABSTRACT:
A phenol-formaldehyde color developing resin is used as a partial or complete replacement for the acidic clay color developer hitherto used in loaded self-copying papers for self-adhesive label assemblies. This counteracts desensitization of the backing paper by the adhesives typically used in such assemblies.
