摘要:
Disclosed is a silver halide direct view multicolor photographic element comprising a green record containing a green light sensitized silver halide emulsion and comprising either (a) a magenta dye-forming coupler and a cyan dye-forming coupler in an amount of at least 0.1 mole % of the couplers present in the green record, or (b) a green record having a coupler or couplers sufficient to provide upon development a Status A red density greater than 0.23 as measured using a green light separation exposure at a Status A green density of 1.0.
摘要:
The present invention is a photographic element which includes, in order, a transparent support, at least one silver halide emulsion layer superposed on the support, optionally a white or diffuse reflective layer, and a processing-solution-permeable protective layer on the backside, which protective layer becomes water-resistant in the final product without lamination or fusing. The present invention is also directed to a method of making a photographic print involving developing the photographic element. The resulting print is viewed through the support, which provides protection against scratches and stains, while the polymeric overcoat provides water and stain protection to the reverse of the print where minor scratches or damage are not critical, since the image is not viewed from this side. Thus, this invention provides for a tough, stain resistant and transparent viewing surface and a stain resistant back side, which is permeable to processing solutions.
摘要:
A direct-positive image-forming photographic material comprises a supporting substrate bearing a light sensitive, nonprefogged silver halide photographic emulsion capable of forming an internal latent image and includes a water-insoluble nucleator. The nucleator is incorporated in the photographic material in the form of a solid particle dispersion to improve the storage stability of the photographic material. The development rate of the photographic material may be increased by use of a developer containing an activator for the nucleator.
