| titleOfInvention | Toner Resin for Electronic Copy |
| abstract | The present invention provides a polycarbonate having a number average molecular weight of 500 to 10000, a glass transition temperature of 30 to 80 ° C, and a hydroxyl group value of 30 mg KOH / g or less, and a component for preparing an electronic copy toner or developer. It relates to the use of said polycarbonate in urethane modified resins used. In addition, the present invention provides a polycarbonate having a polycarbonate and glass transition temperature according to any one of claims 1 to 5 and a hydroxyl group value of 20 to 100 mg KOH / g. Obtainable by reaction of a polymer mixture comprising a synthetic resin with a polyfunctional isocyanate mixture, wherein the weight ratio of polycarbonate and polycondensation resin is from 20:80 to 80:20 and isocyanate groups in the polyisocyanate compound The molar ratio of oxyl groups relates to urethane modified resins of 0.4 to 1.2: 1 as well as toners for electronic copying comprising the urethane modified polycarbonate based resins, and to developers including the toners and optionally carriers. |
