DEFINITION

Classification: 430/572

Multiple sensitizers or supersensitizing:

(under subclass 570) Subject matter in which plural materials are added to an optically sensitive silver compound containing composition to increase the optical sensitivity thereof. The plural materials (a) being capable of sensitizing the silver compound individually, or (b) which cooperate with each other to the extent that the total optical sensitizing effect of the added materials is greater than the sum of the optical sensitizing effects of the added materials taken independently, i.e., there is a synergistic or potentiating effect.
