(FR) STABILISATEURS PHOTOTHERMOGRAPHIQUES
Abstract: front page image
(EN)Photothermographic emulsions have traditionally had slower speeds and a tendency for increased background density with aging, which are undesirable characteristics. The increasing optical density in the background areas is particularly undesirable. The addition of certain classes of aromatic, nitrogen containing compounds to photothermographic emulsions stabilizes the background density of the imaged film and/or increases the speed of the emulsion.
(FR)Les emulsions photothermographiques ont traditionnellement des vitesses basses et une tendance a l"augmentation de la densite de fond lors du vieillissement, ce qui constitue des caracteristiques indesirables. L"augmentation de densite optique dans les zones de fond est particulierement indesirable. L"addition de certaines classes de composes aromatiques contenant de l"azote a des emulsions photothermographiques stabilise la densite de fond d"un film en image et/ou augmente la vitesse de l"emulsion.
