摘要:
A process for the preparation of photogenerating pigments which comprises the sublimation of a pelletized crude photogenerating pigment at a temperature of from about 250.degree. to about 500.degree. C.; depositing the sublimate onto a substrate; subsequently increasing the sublimation temperature by from about 10.degree. to about 100.degree. C. above the first sublimation temperature, and depositing the resulting sublimate onto a substrate.
摘要:
A process including: forming a first chlorogallium phthalocyanine (ClGaPc) in N-methyl-2-pyrrolidone (NMP) to form a ClGaPc (NMP) Type-I product; forming a second chlorogallium phthalocyanine in dimethyl sulfoxide (DMSO) to form a ClGaPc (DMSO) Type-I product; separately dry milling and then wet treating the Type-I products to form respective Type-II products; blending the Type-II products together along with a resin to form a coating mixture; and coating the mixture to form a charge generator layer in an electrostatographic imaging article.
