摘要
Phenol/aldehyde condensation products useful in the development of colored images from colorless dyes are disclosed. The phenol/aldehyde condensation products are produced by the interaction of an alkyl-substituted salicylic acid, an alkyl-substituted phenol, an aldehyde, and a metal source. The phenol/aldehyde condensation products are particularly useful in a photosensitive imaging system in which images are formed by the image-wise reaction of the developer with one or more chromogenic materials, and in carbonless copy paper systems.
