Novel polyesters having p-hydroxybenzoic acid recurring units. |
摘要 |
<p>Novel polyesters having from 15 to 60 mole percent recurring units derived from p-hydroxybenzoic acid may be employed in electrographic developer compositions having
<CHEM>
wherein
x is 0 to 100 mole percent of the prepolymer diol component;
y ist 0 to 100 mole percent of the prepolymer diol component;
toner particles comprising the polyesters. The preferred polyesters comprise polyester prepolymer units and p-hydroxybenzoic acid units which are represented by the formula:
<CHEM>
m is 20 to 100 mole percent of the prepolymer diacid component; and
n is 15 to 60 mole percent. </p> |
