Abstract
A layered imaging member comprised of a photogenerating layer of titanyl phthalocyanine prepared by depositing amorphous titanyl phthalocyanine on a substrate maintained at a temperature of from below 25.degree. to about minus 30.degree. C.; and contacting the substrate product with an aliphatic alcohol.
Claims24
A layered imaging member comprised of a photogenerating layer of titanyl phthalocyanine prepared by depositing amorphous titanyl phthalocyanine on a substrate maintained at a temperature of from below 25.degree. to about minus 30.degree. C. for a period of time until the deposition process is completed;
- and contacting the substrate product with an aliphatic alcohol.
A process for the preparation of titanyl phthalocyanine consisting essentially of depositing amorphous titanyl phthalocyanine on a substrate maintained at a temperature of from below 25.degree. to about minus 30.degree. C. for a period of time until the deposition process is completed;
- and contacting the substrate product with an aliphatic alcohol.
A process for the preparation of titanyl phthalocyanine consisting essentially of depositing amorphous titanyl phthalocyanine on a substrate maintained at a temperature of from below 25.degree. to about minus 30.degree. C. for a period of time until the deposition process is completed;
- subsequently permitting the aforementioned substrate product to attain room temperature;
- and thereafter contacting the substrate product with an alkylalcohol.
A process for the preparation of titanyl phthalocyanine consisting essentially of depositing amorphous titanyl phthalocyanine on a substrate maintained at a temperature of from below 25.degree. to about minus 30.degree. C. for a period of time until the deposition process is completed;
- subsequently permitting the aforementioned substrate product to attain room temperature;
- and thereafter contacting the substrate product with a ketone, a ketone/water mixture or a ketone/water mixture containing an acid.
A process for the preparation of titanyl phthalocyanine Type IV consisting essentially of depositing amorphous titanyl phthalocyanine on a substrate maintained at a temperature of from below 25.degree. to about minus 30.degree. C. for a period of time until the deposition process is completed;
- subsequently permitting the aforementioned substrate product to attain room temperature;
- and thereafter contacting the substrate product with an acid or acid/water mixture.
