ABSTRACT:
2-Amino-2-thiazolinium carboxylates and 4,5-dihydro-6H-1,3-thiazin-3-ium carboxylates are activator-stabilizers in heat-developable and heat-stabilizable photographic materials containing photographic silver salts and photographic silver salt developing agents. An image in such a photographic material is developed and the resulting developed image is stabilized by heating the photographic material.
