Abstract
There is described an intermediate transfer member including a substrate layer comprising a polyimide and a surface layer. The surface layer includes a functionalized polyfluoropolyether and functionalized polybutadiene in a weight ratio of functionalized polyfluoropolyether/functionalized polybutadiene of from about 20/80 to about 80/20 and conductive particles. The method of manufacturing the intermediate transfer member is also described.
Claims17
A intermediate transfer member comprising:
- a substrate layer comprising polyimide;
- and
- a surface layer comprising a polymer consisting of functionalized polyfluoropolyether and functionalized polybutadiene wherein the functionalized polybutadiene is selected from the group consisting of an isocyanate polybutadiene, a hydroxyl polybutadiene, a carboxyl acid polybutadiene, an ester polybutadiene, or an epoxy polybutadiene and wherein said polybutadiene is selected from the group consisting of poly(1,3-butadiene), poly(1,4-butadiene), hydrogenated poly(1,3-butadiene) and hydrogenated poly(1,4-butadiene), in a weight ratio of functionalized polyfluoropolyether/functionalized polybutadiene of from about 20/80 to about 80/20, and conductive particles.
A method of making an intermediate transfer member comprising:
- a) adding and reacting a mixture consisting of functionalized polyfluoropolyether, functionalized polybutadiene wherein the functionalized polybutadiene is selected from the group consisting of an isocyanate polybutadiene, a hydroxyl polybutadiene, a carboxyl acid polybutadiene, an ester polybutadiene, or an epoxy polybutadiene and wherein said polybutadiene is selected from the group consisting of poly(1,3-butadiene), poly(1,4-butadiene), hydrogenated poly(1,3-butadiene) and hydrogenated poly(1,4-butadiene), a solvent, conductive particles and a catalyst to provide a coating composition of functionalized polyfluoropolyether and functionalized polybutadiene in a weight ratio of from about 20 to 80 to about 80 to 20;
- b) coating the coating composition on a polyimide substrate;
- and
- c) curing the coating composition to form a surface layer.
