Abstract

Benzophenone and substituted benzophenones, such as 4-methylbenzophenone and 2, 4-dimethylbenzophenone, are useful as dry vaporizable materials in a distillation printing process. In this process, the back of an original document is either coated with a vaporizable material or brought into contact with an intermediate sheet coated with the vaporizable material.
