    摘要: The present invention provides a matte process employing an improved backing screen having particular application for use in composite photography. In particular, the present invention relates to color difference composite photography, whether still, motion picture, video, solid state digital electronic or electrophotographic imaging, in which foreground and background scenes are separately recorded and subsequently combined using known “blue screen” or special color background techniques to form a single image. The present invention includes a biaxially stretchable fabric of synthetic fibers treated with a dye formulation, including fluorescence which is reactive to the visible spectrum, to achieve any of a variety of specific spectral loci and luminances, for the purpose of providing a precise chromatic actinic stimulus response for a silver halide photographic film, or similar response for electronic imaging devices. The selected backing is deployed in a support such that the fabric is stretched to a smooth, featureless surface and then illuminated. Foreground subject matter interposed between the camera and the backing or directly on the backing will therefore be readily distinguished and “matted” for compositing by methods well known to the art. In a further aspect of the present invention, the light emitting characteristics of the fluorescent matte fabric of the present invention may be advantageously relied upon to obtain the desired lighting effect in, for example, underwater photography. In yet another embodiment of the present invention, the matte fabric of the present invention may be configured to cover objects or parts of a person in a field of view.

    摘要: Process for imparting to polyamide substrates resistance to staining by acid dyes which is durable to shampooing and resistance to yellowing caused by exposure to UV and/or NO.sub.x, comprising applying to said substrate (A) one or more epoxy resins and (B) a polymeric stain-resist agent consisting essentially of (i) copolymers containing more than 75 weight percent methacrylic acid and less than 25 weight percent of one or more other ethylenically unsaturated monomers, or (ii) polymers prepared by polymerizing (a) methacrylic acid or (b) mixtures of methacrylic acid and one or more other ethylenically unsaturated monomers, in the presence of a sulfonated hydroxyaromatic-formaldehyde condensation product.
