ABSTRACT:
A composition of matter including an onium salt and a method of forming images. The onium salt has a chromophore which absorbs ultraviolet radiation, an S, Se, As, N or P atom which is free of substituents exhibiting a higher energy occupied molecular orbital than the chromophore; an insulating group which links the chromophore to the S, Se, As, N or P atom of the salt and substantially prevents .pi. resonance from the chromophore through the S, Se, As, N or P atom; and an anion. The onium salt is capable of forming a Bronsted acid upon exposure to ultraviolet radiation in the presence of a proton source. In the method of forming images, the onium salt is exposed to ultraviolet radiation in the presence of a proton source, to convert said onium salt to a Bronsted acid.
