AUFZEICHNUNGSMATERIAL MIT ELEKTRISCH LEITENDER BZW. ANTISTATISCHER SCHICHT

摘要

Recording materials are described comprising a support of paper or of synthetic polymer and an electroconductive layer coated on at least one side of the support. This electroconductive layer has a surface resistance lower than 1011 Ohms/sq. and consists of or includes a major proportion of a polymer resulting from the reaction of epihalohydrin with polyethyleneimine in the presence of an organic tertiary amine. This polymer is soluble in water and is rendered insoluble by heating at about 100 DEG C. The electroconductive layer may be used as an antistatic layer in a photographic silver halide recording material. When covered with a photoconductive coating the material may be used in electrophotographic recording. With an insulating layer applied thereon, the material may be used for electrographic recording.
