ABSTRACT:
A light-sensitive vesicular imaging composition comprising a vesiculating agent which liberates gas upon exposure to activating radiation, and a binder which is a sulfonamide polymer having the sulfur-nitrogen linkage either in the polymer chain or as a pendant moiety. The composition is coated as a thin film. Imagewise irradiation of the element causes gas bubbles to be released in the exposed areas, which bubbles may be developed by overall heating to a visible record.
