Patent ID: 8076427

Claim:
A release fluid comprising a linear polymer and an amine-functional hyperbranched polymer having the structure of Formula I: [(OR 1 ) 3 SiCH 2 —] x [(OR 2 ) 2 (R 4 )Si(CH 2 —)] y [(OR 3 )(R 5 ) 2 Si(CH 2 —)] z [(R 6 ) 3 Si(CH 2 —)] n wherein R 1 , R 2 , and R 3 are selected from the group consisting of H, CH 3 , alkyl, aryl, alkylaryl, trimethylsilane, dimethylsilane, methylsilane, a polysiloxane oligomer or polymer, or an amine-, mercapto-, or fluorine-containing polysiloxane oligomer or polymer; R 4 , R 5 , and R 6 , are selected from the group consisting of CH 3 , alkyl, aryl, alkylaryl, alkylamino, alkylmercapto, fluoroalkyl; x=0-400, y=0-400, z=0-400, n=0-400, wherein at least one of x, y, z, and n is greater than 0 and x+y+z+n is selected so that the hyperbranched polymer achieves a fluid viscosity of from about 10 cSt to about 1000 cSt at room temperature; the hyperbranched polymer being present in an amount of from about 25 percent to about 50 percent of the release fluid, wherein said hyperbranched polymer reduces viscosity of the release fluid to substantially prevent toner offset.
