Title (EN) TONER BINDER AND TONER
(FR) LIANT POUR TONER ET TONER
(JA) トナーバインダーおよびトナー
Abstract:
(EN) The purpose of the present invention is to provide an excellent toner binder and an excellent toner, which have high gloss, maintain anti-offset properties, and also satisfy all of the following: low-temperature fixability, pulverizability, image strength, and heat resistance preservability. This toner binder contains a non-linear polyester modified resin (A), and is characterized in that the non-linear polyester modified resin (A) is a modified resin in which polyesters are crosslinked by carbon-carbon bonds, and has a loss tangent tanδ of 2-20 over the entire temperature range of 110-130°C.
(FR) La présente invention a pour objet de proposer un excellent liant pour toner et un excellent toner, qui présentent une brillance élevée, maintiennent des propriétés anti-décalage et satisfont également tous les critères suivants: aptitude à la fixation à basse température, aptitude à la pulvérisation, intensité d'image et aptitude à préserver la résistance à la chaleur. Le présent liant pour toner contient une résine modifiée de polyester non linéaire (A), et est caractérisé en ce que la résine modifiée de polyester non linéaire (A) est une résine modifiée dans laquelle des polyesters sont réticulés par des liaisons carbone-carbone, et présente une tangente de pertes tan δ de 2 à 20 sur toute la plage de température de 110 à 130°C.
(JA) 本発明の目的は、高い光沢を有しながら耐オフセット性を維持しつつ、低温定着性、粉砕性、画像強度、耐熱保存性のすべてを満足する優れたトナーバインダーおよびトナーを提供することである。 本発明のトナーバインダーは、非線形ポリエステル変性樹脂(A)を含有するトナーバインダーであって、上記非線形ポリエステル変性樹脂(A)は、ポリエステルが炭素-炭素結合により架橋された変性樹脂であり、110~130℃のすべての温度範囲における損失正接tanδが2~20であることを特徴とする。
