Title (EN) ELECTROPHOTOGRAPHIC TONER
(FR) ENCRE ÉLECTROPHOTOGRAPHIQUE
(JA) 電子写真用トナー
Abstract:
(EN) The present invention addresses the problem of providing electrophotographic toner that has excellent storability, and excellent offset resistance and low-temperature fixing properties during printing, and has few substances that are the cause of dust, and contamination and odors over time inside copying machines and printers. The present invention pertains to electrophotographic toner characterized by containing an ethylene copolymer that contains 80 to 99.5 mol% of structural units derived from ethylene (a), and 0.5 to 20 mol% of structural units derived from a cyclic olefin with at least eight carbons (b) [where (a) + (b) = 100 mol%], and satisfies requirements (i) the intrinsic viscosity [η] ranges from 0.01 to 0.50 dl/g, and (ii) the crystallinity ranges from 50 to 90%.
(FR) La présente invention aborde le problème de fourniture d'encre électrophotographique qui a une excellente aptitude au stockage et une excellente résistance au maculage et des propriétés de fixation à basse température au cours de l'impression. L'encre a peu de substances qui sont la cause de poussières, de contaminations et d'odeurs au cours du temps dans des copieurs et des imprimantes. La présente invention se rapporte à une encre électrophotographique caractérisée en ce qu'elle contient un copolymère d'éthylène composé de 80 à 99,5 % en moles d'unités structurelles dérivées de l'éthylène (a), et de 0,5 à 20 % en moles d'unités structurelles dérivées d'une oléfine cyclique avec au moins huit atomes de carbone (b) [où (a) + (b) = 100 mol %]. L'encre électrophotographique satisfait également aux paramètres (i) de viscosité intrinsèque [η] est comprise entre 0,01 et 0,50 dl/g et (ii) de cristallinité entre 50 à 90 %.
(JA)  本発明の課題は、保存性に優れ、また、印刷時の耐オフセット性や低温定着性に優れ、複写機やプリンター機内の経時汚染や臭気、ダストの原因物質の少ない電子写真用トナーを提供することであり、本発明は、エチレンから導かれる構成単位(a)を80~99.5モル%、および、炭素数8以上の環状オレフィンから導かれる構成単位(b)を0.5~20モル%〔(a)+(b)=100モル%とする。〕含み、要件(i)極限粘度〔η〕が0.01~0.50dl/gの範囲、および(ii)結晶化度が50~90%の範囲にあるエチレン共重合体を含むことを特徴とする電子写真用トナーに関する。
