Study on Tronsporen Base Material

Part 1
Antistatic Treatment of Cellulose Diacetate Film

Abstract

As a study on the flexible bases for the electrophotographic transparencies, the effects of several antistatic agents on the electrical properties of cellulose diacetate (CDA) films were examined.
Effective agents for CDA were some cationic surfactants having Cl^- ions (e. g. stearaimidopropyl dimethyl-β-hydroxyethyl ammonium chloride) and an inorganic coating agent namely Colcoat. Anionic and nonionic surfactants were less effective in comparison with the foregoing two.
From the view point of transparency, however, Colcoat or nonionic surfactants were preferable and their combination was found to be practical.
A transparent electrophotography film which was consisted of a polymeric photoconductive layer and a CDA base treated with the two agents gave a good results in the potential decay test and the visual image printing.
