Patent number: 5891613Abstract: A silver halide light sensitive photographic element is disclosed comprising a support bearing at least one yellow image forming hydrophilic colloid layer comprising yellow image dye forming couplers and a substituted bisphenol light stabilizer compound which has a melting point of greater than 20.degree. C., wherein the yellow image forming layer contains less than 10 wt % high boiling permanent solvent relative to the total amount of yellow coupler in the layer. In preferred embodiments of the invention, the yellow image forming layer is substantially free of high boiling permanent solvent. Light stability for yellow image dyes formed in an exposed and processed photographic element may be significantly improved where the yellow dyes are formed in a photographic layer which is substantially free of organic solvents, or which contains only a very low level of organic solvents, in combination with a substituted bisphenol light stabilizer compound which is a solid at room temperature.Type: GrantFiled: August 22, 1997Date of Patent: April 6, 1999Assignee: Eastman Kodak CompanyInventors: Paul L.
