Claims20
An intermediate transfer member consisting of a mixture of a conductive filler, a poly(amideimide) prepared from a (poly(amic acid amideimide) and a phosphite present in an amount of from about 0.01 to about 15 weight percent of total solids.
The intermediate transfer member in accordance with claim 19 wherein said phosphite present in an amount of about 2 weight percent is tributyl phosphite.
The intermediate transfer member in accordance with claim 16 wherein said polymer is present and is selected from the group consisting of a fluoridated ethylene propylene copolymer, a polytetrafluoroethylene, a polyfluoroalkoxy polytetrafluoroethylene, a fluorosilicone, a terpolymer of vinylidene fluoride, hexafluoropropylene, and tetrafluoroethylene and wherein said phosphite is an alkyl phosphite.
An intermediate transfer member consisting of a photoconductor and said member, wherein a xerographic developed toner image is transferred from said photoconductor to said intermediate transfer member and which member consists of a layer of a mixture of a poly(amideimide) prepared from a poly(amic acid-co-amideimide) copolymer, a phosphite, and a conductive filter component, and wherein the poly(amic acid-co-amideimide) copolymer is encompassed by the following formulas/structures
- where m and n independently represent the number of repeating segments, where m is a number of from about 100 to about 1,000, and n is a number of from about 100 to about 1,000 and wherein said phosphite is selected from the group consisting of alkyl phosphites, aryl phosphites, diaryl phosphites, triaryl phosphites, alkyl diaryl phosphites, and dialkyl aryl phosphites, each present in an amount of from about 0.1 to about 10 weight percent based on the total solids and an optional polymer.
An intermediate transfer member consisting of a photoconductor and said member, wherein a xerographic developed toner image is transferred from said photoconductor to said intermediate transfer member and which member consists of a mixture of a phosphite, a poly(amideimide) prepared from a poly(amic acid-co-amideimide) copolymer, and a conductive carbon black component, which member possesses a break strength of from about 120 to about 200 Mega Pascals, and resists breaking when folded, and wherein the poly(amic acid-co-amideimide) copolymer is encompassed by the following formulas/structures
- wherein m is a number of from about 200 to about 400, and n is a number of from about 200 to about 400, and wherein said phosphite present in an amount from about 0.01 to about 15 weight percent of total solids is dibenzyl phosphite, dibutyl phosphite, tributyl phosphite, diethyl phosphite, diisobutyl phosphite, dimethyl phosphite, diphenyl phosphate, triethyl phosphite, trihexyl phosphite, triisodecyl phosphite, triisopropyl phosphite, trimethylpropane phosphite, trimethyl phosphite, trioctyl phosphite, trioleyl phosphite, triphenyl phosphite, tris(2,4-di-tert-butylphenyl) phosphite, tris(2-ethylhexyl) phosphite, tristearyl phosphite, tri-o-tolyl phosphite, or tri-p-tolyl phosphite.
