Title:
TONER BINDER AND TONER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2010/114020
Kind Code:
A1
Abstract:
Disclosed is a toner binder which has high storage stability and can achieve both of good low-temperature fixability and good hot offset resistance (a broadened fixing temperature range). Specifically disclosed is a toner binder comprising, as constituting units, a carboxylic acid component (x) and a polyol component (y), wherein the component (x) comprises two or more kinds of dicarboxylic acids (x1), selected from among aromatic dicarboxylic acids and ester-forming derivatives of the same, in a total amount of 80 mol% or more and a trivalent or higher polycarboxylic acid (x2); the component (y) comprises a polyester resin (P) which is constituted by a polyester resin (A) comprising 80 mol% or more of an aliphatic diol (y1) having 2 to 10 carbon atoms optionally together with a linear polyester resin (B); and the storage modulus at 150oC [G'150] of the resin (A) is 20000 dyn/cm2 or more and the ratio of [G'150] to the storage modulus at 180oC [G'180] thereof, i.e., [G'150]/ [G'180], is 15 or less.
