Abstract
Dielectric sealing of porous anodized aluminum, in which moisture in the pores of the coating formed by hardcoat anodizing is removed, and the porous anodized surface then impregnated with a water insoluble metallic salt. The impregnant material is a compound of a Group II or III metal with a long chain fatty acid containing between 8 and 32 carbon atoms, saturated or unsaturated. The impregnant material may be applied as a hot melt or in solution; in the former case, any excess material is removed from the surface. The resulting product has excellent resistivity and dielectric properties, and maintains these properties at elevated humidities. As a final step the surface may be polished to provide favorable toner release characteristics during pressure transfer.
