Abstract
An intermediate transfer member, such as a belt, that includes, for example, a supporting substrate, a silane first intermediate layer, and contained on the silane layer a second layer of a self crosslinking acrylic resin; a mixture of a glycoluril resin and an acrylic polyol resin; or a mixture of a glycoluril resin and a self crosslinking acrylic resin.
Claims28
An intermediate transfer member consisting of a supporting substrate, a silane first intermediate layer, and contained on the silane layer a second layer of an optional acid catalyst, and a mixture of a glycoluril resin and an acrylic polyol resin, or a mixture of a glycoluril resin and a crosslinked acrylic resin, an optional outer release layer positioned on said second layer, and wherein said intermediate transfer member accepts a xerographic developed toner image from a photoconductor, and subsequently transfers said image to a substrate.
An intermediate transfer member consisting of and in sequence, of a polyimide supporting substrate, a first intermediate adhesive silane layer, and contained on the silane layer a second layer selected from the group consisting of a crosslinked mixture of a glycoluril resin and an acrylic polyol resin, and a crosslinked mixture of a glycoluril resin and a crosslinked acrylic resin, wherein said crosslinking is from about 50 to about 100 percent;
- said crosslinked acrylic resin possesses a weight average molecular weight (Mw) of from about 120,000 to about 200,000, said glycoluril resin is represented by
- each R group is alkyl with from about 1 to about 6 carbon atoms;
- and said silane is an aminosilane selected from 3-aminopropyl triethoxysilane, N,N-dimethyl-3-aminopropyl triethoxysilane, N-phenylaminopropyl trimethoxysilane, triethoxysilylpropylethylene diamine, trimethoxysilylpropylethylene diamine, trimethoxysilylpropyldiethylene triamine, N-aminoethyl-3-aminopropyl trimethoxysilane, N-2-aminoethyl-3-aminopropyl trimethoxysilane, N-2-aminoethyl-3-aminopropyl tris(ethylethoxy)silane, p-aminophenyl trimethoxysilane, N,N′-dimethyl-3-aminopropyl triethoxysilane, 3-aminopropylmethyl diethoxysilane, 3-aminopropyl trimethoxysilane, N-methylaminopropyl triethoxysilane, methyl[2-(3-trimethoxysilylpropylamino)ethylamino]-3-propionate, (N,N′-dimethyl 3-amino)propyl triethoxysilane, N,N-dimethylaminophenyl triethoxysilane, or trimethoxysilyl propyldiethylene triamine;
- wherein the thickness of said supporting substrate is from about 50 to about 400 microns;
- the thickness of said silane layer is from about 0.01 to about 5 microns;
- and the thickness of said second layer is from about 5 to about 150 microns;
- and wherein the supporting substrate, the silane layer, and the second layer contain a conductive component of carbon black, a polyaniline, a metal oxide, each present in an amount of from 1 to about 50 weight percent, or mixtures thereof, and wherein said intermediate transfer member accepts a xerographic developed toner image from a photoconductor, and subsequently transfers said image to a substrate.
An intermediate transfer belt consisting of and in sequence, of a polyimide supporting substrate, an adhesive silane layer, and contained on the silane layer a second layer of a glycoluril resin and an acrylic polyol resin and wherein said glycoluril resin is represented by
- wherein each R group is alkyl with from about 1 to about 6 carbon atoms;
- and said silane is an aminosilane selected from the group consisting of 3-aminopropyl triethoxysilane, N,N-dimethyl-3-aminopropyl triethoxysilane, N-phenylaminopropyl trimethoxysilane, triethoxysilylpropylethylene diamine, trimethoxysilylpropylethylene diamine, trimethoxysilylpropyldiethylene triamine, N-aminoethyl-3-aminopropyl trimethoxysilane, N-2-aminoethyl-3-aminopropyl trimethoxysilane, or N-2-aminoethyl-3-aminopropyl tris(ethylethoxy)silane, and wherein said intermediate transfer member accepts a xerographic developed toner image from a photoconductor, and subsequently permits transfer of said image to a substrate.
