Abstract: front page image
(EN)Provided is a toner binder having excellent charging characteristics and blocking resistance, and an increased range of fixing temperatures when used as a toner. The present invention is a toner binder containing a polyester resin (P) comprising one or more types of polyester resin obtained by polycondensation of a carboxylic acid component (x) and an alcohol component (y), wherein at least one type (P1) of (P) contains 50 to 95 mol% of a C2-4 aliphatic diol (y1) in the alcohol component (y), and (P) satisfies expressions (1) and (2). (1): 11.5 ≤ SP value [(cal/cm3)1/2] of (P) ≤ 13.0 (2): 5.2 ≤ HLB value (by Oda method) of (P) ≤ 7.1
(FR)La présente invention concerne un liant de toner présentant d'excellentes caractéristiques de charge et résistance au blocage, ainsi qu'une plus grande plage de températures de fixage lorsqu'on l'utilise comme toner. La présente invention concerne un liant de toner contenant une résine de polyester (P) contenant un ou plusieurs types de résine de polyester obtenue par polycondensation d'un constituant d'acide carboxylique (x) et d'un constituant d'alcool (y), au moins un type (P1) de (P) contenant de 50 à 95 % en mole d'un diol aliphatique C2-4 (y1) dans le constituant d'alcool (y), et (P) satisfaisant les expressions (1) et (2). (1) : 11,5 ≤ valeur SP [(cal/cm3)1/2], avec (P) ≤ 13,0 (2) : 5,2 ≤ valeur HLB (selon la méthode Oda), avec (P) ≤ 7,1
(JA) トナーとして用いたときの定着温度幅の増大と耐ブロッキング性、帯電特性に優れたトナーバインダーを提供する。本発明は、カルボン酸成分(x)とアルコール成分(y)とが重縮合されてなる1種以上のポリエステル樹脂で構成されるポリエステル樹脂(P)を含有するトナーバインダーであって、(P)の少なくとも1種(P1)がアルコール成分(y)中に炭素数2~4の脂肪族ジオール(y1)を50~95モル%含有し、(P)が次の式(1)および(2)を満たすトナーバインダーである。 11.5≦(P)のSP値[(cal/cm1/2]≦13.0 ・・・(1) 5.2≦(P)のHLB値〔小田法による〕≦7.1 ・・・(2)
