    摘要： A process for the preparation of hydroxygallium phthalocyanines which comprises hydrolyzing a gallium phthalocyanine precursor pigment by dissolving said hydroxygallium phthalocyanine in a strong acid and then reprecipitating the resulting dissolved pigment in basic aqueous media; removing any ionic species formed by washing with water, concentrating the resulting aqueous slurry comprised of water and hydroxygallium phthalocyanine to a wet cake; removing water from said slurry by azeotropic distillation with an organic solvent, and subjecting said resulting pigment slurry to mixing with the addition of a second solvent to cause the formation of said hydroxygallium phthalocyanine polymorphs.

    摘要： A method of making a multichromal sphere includes the steps of preparing a composition of at least (1) a matrix material and (2) at least two sets of particles, each of the sets of particles having a color different from at least one of another of the sets of particles and a segregation (e.g., an electrical or magnetic) property different from at least one of another of the sets of particles, encapsulating the composition within a shell to form an encapsulated sphere, immobilizing the encapsulated sphere in a manner to restrict at least rotation of the encapsulated sphere, subjecting the immobilized encapsulated sphere to an external field associated with the segregation property different among the sets of particles, under conditions in which the sets of particles are able to migrate within the matrix material, thereby producing color segregation in the immobilized encapsulated sphere, and solidifying the matrix material while substantially maintaining the color segregation. In the multichromal spheres, each of the sets of particles is segregated within a separate segment of the solidified matrix material of the core on the basis of the different segregation property.
