ABSTRACT:
An activator precursor, which is preferably an activator-stabilizer precursor, containing a base portion and an acid portion has improved properties when the acid portion is a 2-carboxycarboxamide. The activator precursors are useful in photographic materials which are responsive to heat for processing. The activator stabilizers have improved coating properties and do not release undesirable volatile materials upon heating.
