Abstract
Abstract An intermediate toner transfer component comprising a substrate and thereover a coating comprised of a volume grafted elastomer, which is a substantially uniform integral interpenetrating network of a hybrid composition of a fluoroelastomer and a polyorganosiloxane, said volume graft having been formed by dehydrofluorination of said fluoroelastomer by a nucleophilic dehydrofluorinating agent, followed by addition polymerization by the addition of an alkene or alkyne functionally terminated polyorganosiloxane and a polymerization initiator.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
36 words
An intermediate toner transfer component comprising a substrate and thereover a coating comprised of a volume grafted elastomer which is a substantially uniform integral interpenetrating network of a hybrid composition of a fluoroelastomer and a polyorganosiloxane.
Claim 2
Dependent Claim
44 words
A toner transfer component in accordance with claim 1, said volume graft having been formed by dehydrofluorination of said fluoroelastomer by a nucleophilic dehydrofluorinating agent, followed by addition polymerization by the addition of an alkene or alkyne functionally terminated polyorganosiloxane and a polymerization initiator.
Claim 3
Dependent Claim
27 words
A toner transfer component in accordance with claim 1 or claim 2, wherein said fluoroelastomer is selected from the group consisting of poly(vinylidene fluoride-hexafluoropropylene) and poly(vinylidene fluoride-hexafluoropropylene-tetrafluoroethylene).
Claim 4
Dependent Claim
74 words
A toner transfer component in accordance with any one of claims 1 to 3, wherein said polyorganosiloxane has the formula: wherein R is an alkyl, alkenyl or aryl, or an aryl group substituted with an amino, hydroxy, mercapto or alkyl or alkenyl group, the functional group A is an alkene or alkyne, an alkene or alkyne substituted with an alkyl or aryl, and n is a number of from about 2 to about 350.
Claim 5
Dependent Claim
59 words
A toner transfer component in accordance with claim 2, wherein said dehydrofluorinating agent is selected from the group consisting of primary, secondary and tertiary aliphatic and aromatic amines, where the aliphatic and aromatic groups contain from about 2 to about 15 carbon atoms, and aliphatic and aromatic diamines and triamines contain from about 2 to about 15 carbon atoms.
Claim 6
Dependent Claim
32 words
A toner transfer component in accordance with claim 5, wherein said amine dehydrofluorinating agent is selected from the group consisting of N-(2-aminoethyl-3-aminopropyl)-trimethoxy silane, 3-(N-styrylmethyl-2-aminoethylamino) propyltrimethoxy silane hydrochloride and (aminoethylamino methyl) phenethyltrimethoxy silane.
Claim 7
Dependent Claim
16 words
A toner transfer component in accordance with claim 2, wherein the polymerization initiator is a peroxide.
Claim 8
Dependent Claim
23 words
A toner transfer component in accordance with claim 7, wherein the peroxide is selected from the group consisting of benzoyl peroxide and azoisobutyronitrile.
Claim 9
Dependent Claim
28 words
A toner transfer component in accordance with any one of claims 1 to 8, including an intermediate adhesive layer located between the overcoating elastomer and a supporting substrate.
Claim 10
Independent Claim
63 words
A method of imaging comprising forming a latent image in an electrographic imaging or printing apparatus containing a photoconductive imaging member, developing the image with a dry or a liquid toner composition, transferring the image to the intermediate transfer component of any one of claims 1 to 9, and transferring the developed image to a suitable substrate, followed by affixing the image thereto.
