Abstract
Disclosed is a fusing release agent comprising the reaction product of a primary- or secondary-amino-functionalized polyorganosiloxane oil and a low molecular weight, non-sterically-hindered aldehyde or ketone
Claims21
A fusing release agent comprising the reaction product of (a) a primary- or secondary-amino-functionalized polyorganosiloxane oil and (b) a compound which is a low molecular weight, non-sterically-hindered aldehyde or ketone, said reaction occurring at a temperature of from about 300° F. to about 550° F., wherein the aldehyde or ketone is of the formula
- wherein each of R21 and R22, independently of the other, is an alkyl group, wherein on of R21 and R22 can be a hydrogen atom.
A fusing release agent comprising the reaction product of (a) a primary- or secondary-amino-functionalized polyorganosiloxane oil and (b) a compound which is a low molecular weight, non-sterically hindered aldehyde or ketone, said reaction occurring at a temperature of from about 300° F. to about 550° F., wherein the reaction product is of the formula
- wherein R1, R2, R3, R4, R5, R6, R7, R8, and R9 each, independently of the others, are alkyl or arylalkyl groups, wherein one or more of R4, R5, and R9 can also be a polyorganosiloxane chain with from 1 to about 100 repeat diorganosiloxane monomer units, R10 is an alkyl or arylalkyl group, each of R21 and R22, independently of the other, is an alkyl group, wherein one of R21 and R22 can also be a hydrogen atom, and p and n are each integers representing the number of repeat monomer units, wherein p must be at least 1 in at least some of the polyorganosiloxane molecules.
A fuser member comprising a substrate, a layer thereover comprising a polymer, and, on the polymeric layer, a coating of a release agent comprising the reaction product of (a) a primary- or secondary-amino-functionalized polyorganosiloxane oil and (b) a compound which is a low molecular weight, non-sterically-hindered aldehyde or ketone, wherein the aldehyde or ketone is of the formula
- wherein each of R21 and R22, independently of the other, is an alkyl group, wherein one of R21 and R22 can also be a hydrogen atom.
A fuser member comprising a substrate, a layer thereover comprising a polymer, and, on the polymeric layer, a coating of a release agent comprising the reaction product of (a) a primary- or secondary-amino-functionalized polyorganosiloxane oil and (b) a compound which is a low molecular weight, non-sterically-hindered aldehyde or ketone, wherein the reaction product is of the formula
- wherein R1, R2, R3, R4, R5, R6, R7, R8, and R9 each, independently of the others, are alkyl or arylalkyl groups, wherein one or more of R4, R5, and R9 can also be a polyorganosiloxane chain with from 1 to about 100 repeat diorganosiloxane monomer units, R10 is an alkyl or arylalkyl group, each of R21 and R22, can also be a hydrogen atom, and p and n are each integers representing the number of repeat monomer units, wherein p must be at least 1 in at least some of the polyorganosiloxane molecules.
