    摘要： A pigment composition is composed of an intimate mixture of an organic pigment and a polymer. The content of the organic pigment is 75-95 wt. % based on the whole pigment composition. Monomers which form the polymer include 0-40 wt. % of styrene, 20-70 wt. % of a methacrylic ester and 20-50 wt. % of methacrylic acid. The total proportion of styrene, the methacrylic ester and methacrylic acid is at least 85 wt. % of the entire monomers. The pigment composition is prepared by mixing the organic pigment with an aqueous alkaline solution, which contains the polymer and an alkali metal salt, alkali metal hydroxide, lower amine or ammonium, to form an aqueous dispersion. The organic pigment and polymer are then subjected to coprecipitation, preferably, by lowering the pH of the aqueous dispersion beyond 7.0.

    摘要： This invention relates to the use of certain co-solvents in cellulose amine N-oxide solutions, which co-solvents increase the cellulose dissolution rate; lower the temperatures necessary to reasonably form a solution; lower the viscosity of the solution; provide solutions with improved color, amine oxide stability, and cellulose stability, provide a solution with improved flow characteristics; increase solution processability, e.g. wet spinning; permit the replacement of amine oxides by a less expensive co-solvent; and are recoverable and reusable in cellulose dissolution and processing.The co-solvents of the invention comprise compounds, miscible with cellulose-dissolving amine N-oxides, containing primary, or combinations of primary and secondary, amino groups wherein the amino groups are bonded to alkyl, alicyclic, dialkyl ether or alkyl/alicyclic radical(s) and wherein the number of carbon atoms divided by the number of primary amino groups is approximately equal to or less than 4; or#C/#NH.sub.2 .ltorsim.4and the number of primary amino groups divided by the number of secondary amine radicals is equal to or greater than 1; that is#NH.sub.2 /#NHR.gtoreq.1.

    摘要： Water-soluble polymers are rapidly dissolved in water by dispersing finely divided particles of the polymer into a liquid carrier in which the polymer is insoluble to form a suspension. The suspension is then added to water in order to release the polymer into the water as discrete particles that rapidly dissolve. The polymer particles are preferably prepared by cryogenic grinding, or another non-molecularly destructive process.
