ALKYL SALICYLATE RESIN FOR CARBONLESS COPY PAPER AND IMAGING USE

摘要

Phenol/aldehyde condensation products useful inthe development of colored images from colorlessdyes are disclosed. The phenol/aldehyde condensa-tion products are produced by the interaction of analkyl-substituted salicylic acid, an alkyl-substi-tuted phenol, an aldehyde, and a metal source. Thephenol/aldehyde condensation products are particu-larly useful in a photosensitive imaging system inwhich images are formed by the image-wise reactionof the developer with one or more chromogenicmaterials, and in carbonless copy paper systems.
