    摘要： Dye diffusion images can be produced by a rapid process in which a first sheet material which contains at least one light sensitive silver halide emulsion on a layer support and at least one color producing compound capable of releasing a diffusible dye on development and/or a second, light insensitive sheet material containing a layer of binder in which is incorporated a salt of a weakly acidic organic compound and a strong organic base is or are moistened with an aqueous liquid and the two sheet materials are then heated to 40.degree.-120.degree. C. with their coated surfaces in contact and subsequently separated.

    摘要： Acrylonitrile/vinyl acetate/styrene copolymers containing a high proportion of acrylonitrile (50-80% by weight) which undergo no discoloration and result in highly transparent products when thermoplastically processed are produced by continuous emulsion copolymerization the monomers in a tube reactor in which comparatively little back mixing occurs (plug flow = laminar flow = non-stationary state). A seed latex having a specified, small particle size with a narrow particle size distribution of the copolymer is obtained; the reaction mixture is then cooled, if necessary, in order to prevent further polymerization as far as possible and continuously transferred into a stirrer vessel while at the same time a stream of monomers consisting of acrylonitrile, vinyl acetate and styrene also having a specified but different percentage composition of monomers than in stage 1 is also fed into this stirrer vessel, and in this second stage of the process, polymerization is carried out at specified temperatures and with specified residence times under stationary conditions, i.e. with back mixing up to a total conversion of 70 to 90%.
