Patent

CA 2147631

Certain squaric acid derivatives and sulfonate esters are useful for the thermochemical generation of acid. The thermal ac- id generators may be used in imaging media in conjunction with acid-sensitive materials which undergo a color change when con- tacted by the acid generated. Preferably, the acid-sensitive materials undergo an irreversible color change, so that the image can be fixed by neutralizing all the acid generated with excess base, thereby preventing further color change in the image during long term storage.
