Title (EN) DIFFUSION TRANSFER RECEIVER
(FR) RECEPTEUR D'IMAGE PAR DIFFUSION
Abstract:
(EN) The invention provides a diffusion transfer receiver comprising a support with a non-light-sensitive image receiving layer coated onto each face thereof, said image receiving layer in each case comprising a catalytic nuclei layer for physical development of transferred complex silver halide and each composite comprising a diffusion modifying active component which is preferably a tone controlling compound. The composites of Side 1 and Side 2 are different constitutions so as to provide receivers suitable for different end users. For example Side 1 can be made suitable for creative designers while Side 2 can be made suitable for pre-sensitized platemakers. The invention also provides a method for improving transmission density of a receiver sheet in a non-light-sensitive image receiving layer of a silver diffusion transfer process which method comprises utilizing in the receiver layer an S-thiuronium alkylene sulphonate transmission density enhancer.
(FR) l'invention concerne un récepteur d'image par diffusion comprenant un support dont toutes les surfaces sont recouvertes d'une couche de réception d'image insensible à la lumière qui comprend dans tous les cas une couche à noyaux catalytiques permettant le développement physique d'un halogénure d'argent complexe transféré, chaque composite comprenant un composant actif de modification de la diffusion qui est de préférence un composé régulateur de ton. Les composites des côtés 1 et 2 sont de compositions différentes de manière à fournir des récepteurs pouvant servir à des utilisations finales diverses. Ainsi, le côté 1 peut être préparé pour des conceptions créatives, tandis que le côté 2 peut servir dans la confection de plaques présensibilisées. L'invention concerne également un procédé permettant d'améliorer la densité de transmission d'une feuille de réception dans une couche de réception d'image insensible à la lumière d'un procédé d'impression à l'argent, lequel procédé comprend l'utilisation dans la couche de réception d'un agent d'augmentation de la densité de transmission constitué de sulphonate à l'alkylène de S-thiuronium alkylène.
