Abstract
A process for producing a thin film comprising electrotreating a dispersion or solution obtained by dispersing or dissolving a hydrophobic substance powder in an aqueous medium with a surfactant having a HLB value of 10.0 to 20.0, under conditions for forming a thin film of the hydrophobic substance on a cathode. The thin film of a hydrophobic substance can be formed on base metals such as aluminum, which can be applied to photosensitive materials and the like.
Claims18
A process for producing a thin film comprising electrotreating a dispersion or a solution obtained by dispersing or dissolving a hydrophobic substance powder with a surfactant having a HLB value of 10.0 to 20.0 under conditions for forming a thin film of said hydrophobic substance on a cathode with a potential on the cathode of -0.03 to -10.0 V.
The process for producing a photoconductor for electrophotography, which comprises dispersing or dissolving a hydrophobic substance powder, said powder having an average particle diameter of not more than 10 .mu.m in an aqueous medium with a surfactant having a HLB value of 10.0 to 20.0, said surfactant is a compound other than a ferrocene compound, and subsequently electrotreating the resulting dispersion or solution with an aluminum electrode as a cathode, to form a thin film of said hydrophobic substance on said aluminum electrode.
