Photosensitive material for use in electrophotography

Abstract

The present invention relates to a photosensitive material for use in electrophotography comprising a photoconductive layer on which there is a transparent protective layer consisting essentially of a substance resulting from partial hydrolysis of a mixture of (a) a compound having the following general formula I, (b) a copolymer of a compound having the general formula II with a compound having the general formula III or maleic anhydride and (c) a compound having the general formula IV, (1) General formula I (R.sup.1).sub.l Si(OR.sup.2).sub.m [wherein R.sup.1 is a C.sub.1-4 alkyl radical, vinyl radical, .gamma.-methacryloxypropyl radical, phenyl radical, .gamma.-glycidoxypropyl radical, .gamma.-chloropropyl radical, .gamma.-mercaptopropyl radical, .gamma.-.beta.(aminoethyl).gamma.-aminopropyl radical or .gamma.-aminopropyl radical; R.sup.2 is a hydroxyethylalkyl ether radical or C.sub.1-4 alkyl radical; l is 0-2; and m is 2-4.] (2) General formula II ##STR1## [wherein R.sup.3 is hydrogen or a methyl radical; R.sup.4 is hydrogen or a C.sub.1-4 alkyl radical; n is 1-4; and q is 1-3.] (3) General formula III ##STR2## [wherein R.sup.5 is hydrogen or a methyl radical; R.sup.6 is --COOR.sup.7 (R.sup.7 is hydrogen or a C.sub.1-12 alkyl radical, hydroxyalkyl radical, glycidyl radical or dimethylaminoalkyl radical), --CN, --OCOCH.sub.3, --CONH.sub.2, ##STR3## (4) General formula IV ##STR4## [wherein R.sup.8 is a C.sub.1-4 alkyl radical or phenyl radical; z is 2-25.]
