摘要:
A color photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer containing a 3-anilino-5-pyrazolone type magenta coupler and at least one of the compounds represented by the formula (I) ##STR1## wherein R.sub.1 and R.sub.2 represent each a tertiary alkyl group having 4 to 20 carbon atoms.
摘要:
A compound represented by the structural formula: ##STR1## is representative of the compounds disclosed which are utilized within the silver halide layer of photographic light-sensitive materials. The compounds aid in preventing the fading of dye images which are formed by development of color photographic light-sensitive materials as well as aiding in the prevention of discoloration of non-developed areas. The effects of the compounds are particularly noticeable when utilized in combination with magenta couplers or cyan couplers, and other antifading agents in an amount of 2 to 150% by weight based on the weight of the couplers.
摘要:
A dye image stabilization process for color photographic sensitive elements which comprises processing a color photographic sensitive element containing at least one dye image stabilizer precursor with a solution containing divalent ions of at least one metal selected from Cu, Co, Ni, Pd and Pt is disclosed. Light fastness of dye images is thus improved.

An image pickup apparatus includes a base that has electric conductivity, at least one image pickup element, and at least one fixing member for fixing the image pickup element to the base. The base has at least one conducting portion on the surface thereof on the side of the fixing member, and the image pickup element has a conducting portion on the surface thereof on the side of the fixing member. The fixing member is formed of peelable resin for separating the image pickup element from the base by applying current. The area of the conducting portion of the base is larger than the area of the fixing region between the fixing member and the base.
