    摘要： A conductive substrate and electrostatic recording media which incorporates such a conductive substrate are disclosed. The disclosed conductive substrate and recording media are applicable to electrostatic recording processes, electrophotographic printing processes and the like, and demonstrate excellent resistance to damage by water and other environmental factors. The conductive substrate of the present invention includes a substrate layer with at least one surface thereof having a conductive layer formed thereover. The above mentioned conductive layer has as a principle component an acryl type copolymer formed from polymerizable vinyl monomer of the type shown in chemical structural diagram 1 below in an amount of 10 to 45% by weight of the acryl type copolymer, and at least one other type of polymerizable vinyl monomer, ##STR1## such that in chemical structural diagram 1, R.sub.1 represents a hydrogen atom or a methyl group, R.sub.2 represents an alkylene group, R.sub.3, R.sub.4 and R.sub.5 represent benzyl groups or one to four carbon atom alkyl groups, and X represents chlorine, bromine, CH.sub.3 SO.sub.4 or C.sub.2 H.sub.5 SO.sub.4.

    摘要： The present invention relates to a recording medium which has an electroconductive layer which exhibits strong stable resistance to humidity and water, and provides high precision visual images and color reproduction of superior quality. The electroconductive substrate comprises an electroconductive layer on at least one side, wherein the electroconductive layer contains an electroconductive pigment, a normal salt and a binder; the binder contains 20 to 85 weight % of starch and the normal salt is maintained at 10 to 100 parts by weight with respect to 100 parts by weight of said electroconductive pigment. The recording medium comprises a recording layer which is formed on the electroconductive layer described above, and may contain silicone resin particles therein for further improvement of high prevision visual images.
