Procedure for the Characterization of Zinc Oxide Photocopy Papers

CODEN: JFSCAS

Abstract

A method is presented for the characterization of zinc oxide photocopy papers. The tests include nondestructive physical examinations of weight, pH, and color under ultraviolet light. Chemical tests, consisting of thin-layer chromatographic examination of the sensitizing dyes and infrared spectrophotometry of the binder resins, are carried out on extractions of the photoconductive surface layer. A semiqualitative flow chart has been prepared that permits differentiation of most of the zinc oxide photocopy papers on the basis of the composite of characteristics of 50 papers supplied by eleven manufacturers.
