SULFONYLACETATE ACTIVATOR-STABILIZER PRECURSOR

摘要

An activator-stabilizer precursor compound having an acid portion which is an alpha-sulfonylacetate is useful in a photographic composition which is responsive to heat for processing. The activator-stabilizer precursors are characterized in that their acid byproducts have reduced toxicity and volatility and are substantially inert in a processed photographic element.
