Abstract

L'invention est relative à la photographie. Le procédé selon l'invention permet de fabriquer un produit photographique qui comprend un support 10 de papier à encollage interne, au moins une couche d'encollage 12 en surface obtenue à partie d'une composition aqueuse contenant un cétène dimérisé et, en position adjacente à cette couché d'encollage, une couche 14 obtenue à partir d'une composition aqueuse de colloïde hydrophile protéiné. On obtient ces couches en appliquant les compositions en couches humides superposées puis en séchant ces couches. La couche d'encollage ne contient pas de colloïde hydrophile protéine ou en contient une quantité insuffisante pour réduire notablement le caractère hydrophobe de la couche après séchage. Application à la préparation de produits photographiques résistant à la pénétration des solutions aqueuses de traitement photographique.The invention relates to photography. The process according to the invention makes it possible to manufacture a photographic product which comprises a support 10 of internally sized paper, at least one sizing layer 12 on the surface obtained from an aqueous composition containing a dimerized ketene and, in an adjacent position to this size coating, a layer 14 obtained from an aqueous composition of hydrophilic protein colloid. These layers are obtained by applying the compositions in superimposed wet layers and then drying these layers. The sizing layer does not contain or contains an insufficient hydrophilic colloid protein to significantly reduce the hydrophobic character of the layer after drying. Application to the preparation of photographic products resistant to the penetration of aqueous solutions for photographic processing.
