    摘要： A heat-developable photosensitive material is disclosed having a high image sharpness. The material is comprised of a heat-developable photosensitive layer which includes an organic silver salt, a photocatalyst, and a reducing agent. An antihalation layer is provided on the opposite face of the material with respect to the side intended for imagewise exposure. The antihalation layer contains a photosensitive halogen-containing compound which reduces the pH of the antihalation layer by photolysis and is colored with a dye which causes a change of color when the pH of the antihalation layer is reduced.

    摘要： A silver halide photographic light-sensitive material containing a diffusion resistant coupler, a light-sensitive silver halide and at least one compound represented by the following general formula (I) in the same layer or different layers on a support. ##STR1## wherein R.sup.1 and R.sup.2 independently represent an alkyl group having from 1 to 5 carbon atoms, a hydroxyalkyl group having from 1 to 5 carbon atoms, an alkoxyalkyl group having from 2 to 10 carbon atoms or an alkylsulfonamidoalkyl group having from 2 to 10 carbon atoms; R.sup.3 represents a hydrogen atom, an alkyl group having from 1 to 5 carbon atoms or an alkoxy group having from 1 to 5 carbon atoms; X represents a hydrogen atom or a group capable of being removed with alkali; Y represents ##STR2## and Z represents an alkyl group, an alkenyl group, an aryl group or a heterocyclic group.The compound represented by the general formula (I) is a novel precursor of a color developing agent which provides a sufficiently high color density on development and causes less desensitization as well as less fog or stain formation during storage of any photographic light-sensitive material containing it. A method of forming a color photographic image using the silver photographic light-sensitive material is also disclosed.

    摘要： A novel retarder comprising a long transparent substrate, and up on the substrate, a first and a second optically anisotropic layers formed from a homogenously aligned rod-like liquid crystal compound and having a phase shift substantially equal to n measured and equal to &pgr;/2 respectively at a wavelength of 550 nm; and a first alignment layer having a rubbing axis defining the azimuthal direction of the homogenous alignment in the first anisotropic layer. The angle between the slow axis of the first anisotropic layer and the longitudinal direction of the transparent substrate is 75°, the angle between the slow axis of the second anisotropic layer and the longitudinal direction is 15°, the angle between the slow axis of the second anisotropic layer and the slow axis of the first anisotropic layer is 60° and the azimuthal direction of the homogenous alignment in the first anisotropic layer is substantially orthogonal to the rubbing axis of the first alignment layer.
