    摘要: A process for continuous preparation of zeolite A of constant and homogeneous quality, consisting of instantly and continously mixing a sodium silicate solution and a sodium aluminate solution in the correct proportions and at an elevated temperature followed by transfer of the resulting slurry to a crystallization reactor. The product is recovered from the crystallization reactor washed and dried.

    摘要: A process of forming color images comprises imagewise exposing a silver halide photographic color image-transfer product comprising an image dye-providing compound in the presence of a silver halide developer, and treating the exposed photographic product with an alkaline processing composition in the presence of an amino acid or a combination of an acid and an amine. Color images are achieved having excellent image discrimination (Dmax-Dmin).
