    摘要： A photographic element, and coupler employed therein, comprises a photographic silver halide emulsion layer containing a yellow dye-forming coupler having a the general formula: ##STR1## wherein Z is a ballasted group which splits off on silver halide development which is of such size and configuration to render the coupler non-diffusible in photographic layers, prior to splitting off, andR.sup.1 and R.sup.2 are each individually an alkyl or aryl group whose combined effect is to render the yellow dye formed on coupling sufficiently mobile to produce image smearing.

    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.
