Abstract:
An electrostatic image receptor comprisinga dielectric substrate;a release layer comprising the reaction product of 35 to 80 parts by weight of a base material having the formula (R.sub.3 SiO.sub.1/2).sub.2 (R.sub.2 SiO.sub.2/2).sub.x, wherein each R is independently selected from alkyl groups, aryl groups, and functional groups capable of crosslinking, and at least 3% of R are functional groups capable of crosslinking, and x is an integer greater than 0;more than 0 up to 50 parts by weight of a second material having the formula (R'.sub.3 SiO.sub.1/2).sub.2 (R'.sub.2 SiO.sub.2/2).sub.y, wherein each R' is independently selected from alkyl groups, aryl groups, and functional groups capable of crosslinking, and no more than 2.5% of R' are functional groups capable of crosslinking, and y is an integer of at least 50;more than 0 up to 160 parts by weight of a third material having the formula (R"".sub.3 SiO.sub.1/2).sub.a (R"".sub.2 SiO.sub.2/2).sub.c (R"".sub.n SiO.sub.(4-n)/2).sub.b wherein a, b, and c are integers, a is 3 or greater, b is 5 or greater, c is 0 or greater and 0.25<b/(a+b+c)<0.9; n=0 or 1; and each R"" is independently selected from alkyl groups, aryl groups, and functional groups capable of crosslinking; andoptionally, 5 to 30 parts by weight of a crosslinking agent having the formula (R'"".sub.3 SiO.sub.1/2).sub.2 X(R'"".sub.2 SiO.sub.2/2).sub.z, wherein z is an integer from 0 to 100; X is a single bond, O or a divalent organic linking group; each R'"" is independently selected from alkyl groups, aryl groups, and functional groups capable of crosslinking and 25-100% of R'"" are functional groups capable of crosslinking provided that there are at least 2 functional groups capable of crosslinking per molecule.
