摘要:
Toner fusing rolls having an oil barrier layer composed of a substrate coated with a fluorocarbon-silicone polymeric composition which is obtained by concurrently curing a fluorocarbon copolymer, a nucleophilic fluorocarbon-curing agent and a heat-curable polyfunctional poly(C.sub.1-6 alkyl)phenylsiloxane polymer.
摘要:
Toner fusing members having a surface layer comprising a substrate coated with a fluorocarbon-silicone polymeric composition are obtained by concurrently curing a fluorocarbon copolymer, a nucleophilic fluorocarbon-curing agent and a heat-curable polyfunctional polymethylsiloxane polymer.
摘要:
Toner fusing members coated with cured epoxy-substituted organopolysiloxane compositions are obtained. Such epoxy-substituted organopolysiloxanes are obtained by hydride-addition of a hydride-substituted organopolysiloxane with an unsaturated epoxy compound.
摘要:
Toner fusing members with improved properties are formed with an outer layer comprising a melamine-cured block polyurethane coating composition. Such a (A-B).sub.n' block polyurethane is formed by polycondensation of a diisocyanate, an organopolysiloxane diol and a C.sub.2-20 diol.
摘要:
Toner fusing members with improved properties are formed with an outer layer comprising a melamine-cured polyurethane coating composition. Such a polyurethane is formed by polycondensation of a diisocyanate, and a polysiloxane diol containing units of 2,2-bis(4-hydroxyphenyl) hexafluoropropane.
摘要:
Toner fusing members coated with melamine-cured polyester-amide compositions are obtained wherein the polyester-amide component is a copolymer of one or more organic dicarboxylic acids with 2,2-bis(4-hydroxyphenyl)hexafluoropropane and an aminoalkyl-terminated organopolysiloxane.
摘要:
Toner fusing members coated with melamine-cured phenolic polysfloxanes compositions are obtained. Such a phenolic polysiloxane is obtained by hydride-addition of a hydride-substituted polysiloxane with an alkenyl substituted phenol.
摘要:
This invention provides a release agent consisting of a blend of poly(organosiloxane) fluid and phenol-functionalized poly(organosiloxane) fluid which when used at elevated temperatures does not produce insoluable or undesirable by-products or gellation. The release agent is particularly suited for application to a fuser member for fusing toner images to a receiver.
摘要:
Toner fusing rolls with improved properties are formed with an outer layer comprising an addition-cured silicone elastomer. Such as elastomer is formed by crosslinking hydride substituted organopolysiloxanes and polyimides substituted with unsaturated hydrocarbon radicals.
摘要:
A negative-working photoresist composition comprising, in admixture, (a) dye-loaded or dye-precursor-loaded polymeric particles individually covered with a layer of gelatin that is covalently bonded thereto and (b) a radiation-sensitive dichromate is useful in the preparation of continuous tone dyed imaging elements such as color filter arrays for use in solid state color image sensing devices.
