The p-aminophenol may be present in the photosensitive element or in the processing solution. The onium compound may be present in the photo-sensitive element or image-receiving layer and may be a water-soluble compound or a relatively water-insoluble polymeric compound. The dye imagereceiving sheet may comprise a coacervate mordant (see Ex 4, 7, 9, 11 and 12). The photo-sensitive element may comprise a coacervate dye image-receiving layer and opaque layer of titanium dioxide and carbon between its support and the silver halide layer(s) (see Ex 12). In one embodiment of the invention the colour coupler may be diffusible and form a relatively immobile product upon exposure and development with the p-aminophenol, unreacted coupler and unoxidised p-aminophenol transferring to an imagereceiving layer where they can react with an oxidizing agent or by aerial oxidation, followed by coupling in the presence of the onium compound to form the onium indophenoxide dye. These dye images have improved heat and light stability, spectrophotometric characteristics and reduced staining by the developing agent and emulsion de-sensitization by the colour developing agent is reduced. Onium indophenoxide dye image formation is described and claimed in Specification 1394592.

Abstract: 1,112,403. Apparatus for controlling the stretching of filamentary material. LINEN INDUSTRY RESEARCH ASSOCIATION. 29 Dec., 1964 [27 Sept. 1963 (2)], Nos. 38066/63 and 38067/63. Heading B5B. [Also in Division H2] In apparatus for controlling the relative speed of two pairs of rollers used in the stretching of textile filamentary tow, one of the pairs of rollers has a variable speed drive effected through a variable ratio gear-box which is driven by a constant speed motor and which has a control shaft adapted to be rotated at varying speeds by a servomotor or a variable speed electric motor controlled by the signal from an arbitrary function generator. As illustrated in Figs. 1 and 3, filamentary tow material 10 is passed successively between two pairs of rollers, a constant speed electric motor 20 driving the first pair of rollers 12, 14 via fixed ratio gear-box 22 and driving the second pair of rollers 16, 18 via variable ratio gear-box 24, the effective ratio of which is varied by rotation of control shaft 26 driven by variable speed motor 44. Geared to the control shaft, the position of which shaft determines the effective ratio of the variable ratio gear-box, is the rotor arm of potentiometer 50, the output voltage of which is dependent upon the position of the control shaft; this voltage is compared with the voltage from arbitrary function generator 48, the voltage difference being amplified and fed to the motor driving the control shaft until-the voltage from the potentiometer equals the voltage from the arbitrary function generator, rotation of the control shaft thus being proportional to the voltage from the arbitrary function generator. Feedback loops (not shown) may be included to prevent hunting. The arbitrary function generator, into which is fed the output signal from sawtooth voltage generator 46, develops a voltage which varies cyclically according to a predetermined waveform. A signal equated to the effective ratio of the variable ratio gear-box may be applied to analogue computer 52 and reproduced in chart 54 to indicate variations in the speed of the pair of rollers having variable speed drive and hence variations in the degree of fibre stretch.
