Abstract: A silver halide photographic material comprising a support having thereon at least one silver halide photographic emulsion layer containing at least one sensitizing dye represented by formula (I) and at least one compound represented by formula (II). ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, each represent an alkyl group which may be substituted and at least one of R.sub.1 and R.sub.2 is an acetylaminoalkyl group or an N-alkylcarbamoylaminoalkyl group; and V.sub.1 and V.sub.2, which may be the same or different, each represent a hydrogen atom, an alkyl group, an alkoxy group or a trifluoromethyl group. ##STR2## wherein Z represents a non-metallic atomic group required for forming a heterocyclic ring; M represents a hydrogen atom, an --NH.sub.
Abstract: A photographic recording material which comprises at least one gelatin-containing silver halide emulsion layer and at least one protective layer containing a gelatin derivative, the protective layer being further away from the layer support than each silver halide emulsion layer and 30 to 90% of the amino groups of the gelatin in the gelatin derivative being reacted with a monofunctional acid derivative, and which is hardened with an instant hardener can be produced at high speed and, hence, at high drying temperatures without any reticulation grain occurring during processing.

Abstract: A solid state color image sensing device comprising a semiconductive support having a surface comprising an array of light sensing pixels and superimposed thereon in microregistration a color filter array having at least three sets of dyed filter elements is characterized in that at least one set of the filter elements is formed from a negative-working dyeable photoresist composition comprising, in admixture,(a) a poly(vinyl alcohol) binder,(b) a radiation-sensitive dichromate, and(c) a polymeric mordant comprising recurring units derived from a quaternized N-vinylimidazole.Color filter elements prepared from the dyeable photoresist composition have high resolution, excellent clarity and dye uptake, and low absorbance of blue light and thus are particularly useful in high quality high resolution solid state color imaging sensors having excellent thermal and light stability. A method of making the above-described device is disclosed.
Abstract: Disclosed is a method of preparing and printing custom artwork such as, for example, photo greeting cards, allowing the creation of calendars, business cards, and the like using a plurality of colors. In the method, after all of the preparatory typesetting and artwork has been completed, special color filters are adhered to the base side of the high contrast film negative which is created from the pasted-up type and artwork. These filters are chosen based upon the desired finished product colors. The final color created is the photographic complement of the filter(s) used.
