    摘要: In accordance with one embodiment of the invention, a photographic element is disclosed comprising a silver halide emulsion layer having associated therewith an acetanilide-based yellow dye forming coupler and a stabilizer compound of the formula S-I: wherein R0 represents an aryl or heterocyclic group; Ra is H or a substituent group; L represents an alkylene linking group and p represents 0 or 1; and Rb is a substituent group, provided that substituent groups represented by Ra and Rb may be joined to form a ring. The presence of substituted amine compounds of formula S-I improves the efficiency of dye formation reaction for acetanilide-based couplers. When used in combination with known bis-phenolic stabilizers, substantial improvements in the light stability of the image dyes can be also be obtained. Accordingly, photographic elements of the present invention upon exposure and photographic processing exhibit good activity and yield yellow dye images that have low fading when exposed to light.

    摘要: A method of making a polymeric compound, comprising discrete particles responsive to an external stimulus, that is resistant to aggregation in high-shear fields, which includes the addition of a polymerization initiator to a reaction mixture comprising a monomer corresponding to the polymeric compound, wherein the method comprises the portion-wise addition of aliquots of a cross-linking agent to the reaction mixture, wherein an aliquot of the cross-linking agent is added to the reaction mixture both before the addition of the polymerization initiator and after the polymerization has progressed substantially to completion. The polymer particles are largely immune to the effects of transient shear rates at least as high as 106 s−1, whilst maintaining their thermal responsiveness and being present at moderate concentration. The structural and chemical modifications brought by the delayed portion-wise addition of the cross-linking agent allow an improvement in stability in a high-shear field.
