摘要： In preparing an opaque backing layer for a photographic film, superior covering power and coating dispersion stability are obtained by (1) dispersing carbon black in a minor phase of polyvinyl pyrrolidone/vinyl acetate copolymer before addition of a major phase of polyvinyl alcohol, and (2) delaying the addition of surfactant or coating aids until after complete mixing of the polyvinyl alcohol with the solid carbon black dispersion. This coating dispersion is particularly useful for the preparation of a dischargeable opaque backing layer for a diffusion transfer film element.

摘要： A dye preparation consists of a water-soluble acid dye and a water-insoluble basic carrier. The carrier consists of crosslinked polymer particles of average particle diameter of less than 1 .mu.m and contains at least 2 mVal/g of quaternary ammonium or phosphonium groups. The dye reacts with the carrier in an ion exchange reaction and forms a dye polymer latex which can easily isolated in solid form, stored indefinitely and redispersed in water whenever required. It forms a so-called self-dispersing dye preparation. The dye preparation is useful for making dyed layers such as in photographic recording materials.

摘要： Polymer-bound dyes have been prepared by the diazotization of high polymeric [NP(OC.sub.6 H.sub.5).sub.x - (OC.sub.6 H.sub.4 NH.sub.2 -p).sub.y ]n, followed by coupling to phenol, .beta.-naphthol, 6'-NaO.sub.3 S-.beta.-naphthol, and p-aminophenylnaphthalene. These reactions were preceded by model compound studies with the cyclic trimer [NP(OC.sub.6 H.sub.4 NH.sub.2 -p-).sub.2 ].sub.3. In both cases, the aminophenoxy units were generated by reduction of 4-nitrophenoxy groups with the use of PtO.sub.2 and hydrogen. The phosphazene skeleton was unaffected by the reduction, diazotization, and diazo coupling processes. The physical characteristics of the trimers and high polymers are described.

摘要： Polymeric quaternary ammonium betaines; the preparation thereof; and uses therefor. These are illustrated by polymers and copolymers of dicarboxylic anhydrides such as maleic anhydride and copolymers thereof derived from copolymerizable compounds such as olefins, vinyl compound, etc.; a carboxylic acid group of the anhydride polymeric unit being esterified with a quaternary alkanolamine. The polymers are prepared by reacting the anhydride-containing polymer with an alkylene oxide and a tertiary amine to form quaternary alkanolamine esters.
