Abstract (en)
[origin: EP0379893A2] Polypropylene oxides having an OH content of 1 - 3% by weight are suitable as oil formers for non-diffusing colour-donating compounds, for example colour couplers. In the case of comparatively hydrophilic compounds, especially yellow couplers with an -SO2-NH- grouping or a phenolic hydroxyl group, they reduce the tendency to crystallise and the undesired diffusion into adjacent layers. This allows a reduction of the gelatine content. The light stability is improved.
