    Abstract: Development of exposed photographic silver halide emulsion is described wherein development occurs by means of an organometallic complex of a metal capable of changing its valency and an aliphatic aminocarboxylic acid containing at least one mono- or di(carboxyalkyl)aminoalkyl group and at least one hydroxyl group, or a water-soluble salt of the chelating compounds.

    Abstract: A photographic element comprising a glass support and a photosensitive emulsion layer on said support comprising a filmforming proteinaceous colloid is described. The adherence of the emulsion layer to the glass support is enhanced by including the emulsion layer an organic silicon compound having hydrocarbon groups directly or indirectly attached to a silicon atom wherein at least one of the hydrocarbon groups carries a group or atom which has chemical affinity for the free reactive groups of the proteinaceous colloid or which can be cross-linked to the free reactive groups through the intermediary of a cross-linking agent. The adherence of the photosensitive emulsion layer to the glass support is enhanced without affecting the photosensitive properties of the emulsion layer.

    Abstract: Photographic silver halide elements are described which comprise incorporated in a silver halide emulsion layer or another waterpermeable colloid layer a hydroquinone silver halide developing agent precursor of which at least one of the hydroxyl groups of said hydroquinone has been esterified to form a hydrolyzable aliphatic acyloxy radical comprising a quaternary ammonium group. Upon treatment of the exposed elements with an alkaline solution the developing agent precursor hydrolyzes readily to yield the active developing agent so that no delay in development occurs. The resulting developed images are free from spots, do not show fog and possess the desired sensitivity and gradation with normal or even shorter length of development time.
