Abstract: THE LIGHT STABILITY OF COLOR PHOTOGRAPHIC IMAGES IS IMPROVED BY COVERCOATING THE IMAGE CARRYING LAYER WITH A UVPROTECTIVE COATING WHICH CONTAINS A UV-ABSORBING COMPOUND. THE UV-ABSORBING LAYER CONTAINS AS UV-ABSORBENT A 2-PHENOLBENZOTRIAZOLE, THE BENZO RING OF WHICH IS SUBSTITUTED WITH 2 BUTYL GROUPS.

Abstract: The light stability of color photographic images is improved by overcoating the image carrying layer with a UV-protective coating which contains a UV-absorbing compound. The UV-absorbing layer contains as UV-absorbent a 2-phenolbenzotriazole, the benzo ring of which is substituted with at least 1 alkoxy group.

Abstract: PHOTOGRAPHIC LAYERS CONTAINING A LIGHT-SENSITIVE CYCLIC ARYL POLYCARBOXYLIC ACID IMIDE AND A COMPOUND HAVING AT LEAST ONE OLEFINIC DOUBLE BONDS OR HAVING GROUPS CAPABLE OF FORMING OLEFINIC DOUBLE BONDS, UPON EXPOSURE BECOME LESS SOLUBLE OR LESS SWELLABLE UPON EXPOSURE AT THE LIGHTSTRUCK AREAS. A RELEIF IMAGE IS OBTAINED AFTER REMOVAL OF THE UNEXPOSED AREAS.

Abstract: Trimesic aldehydes, which are substituted in the 2-,4- and 6position with chlorine, hydroxy or methoxy, as well as hexamethyl acetals and bisulfite addition products of such aldehydes are useful for hardening gelatin layers especially photographic gelatin layers. The hardening effect is developed by rendering alkaline the gelatin that contains any of these aldehydes.
