(FR) ENCRE POUR JET D'ENCRE
(JA) インクジェットインク
Abstract
(EN)
[Problem] To provide an inkjet ink which has excellent intermittent printability when used for an on-demand type inkjet printer, is unlikely to yield faint printing when printing is resumed, and is unlikely to be blurred or removed, even when repeatedly rubbed with a fingertip or the like after being printed on a metal surface, a low-polar surface, or the like. [Solution] A phenol resin having a softening point of 70-125°C, a tackifier, a coloring agent, and an organic solvent are blended. The organic solvent is preferably an alcohol having 1-3 carbon atoms. As the tackifier, a terpene phenol resin having a hydroxyl value of 10-45 mgKOH/g is preferred in dye-based blending, and a rosin ester resin having an acid value of 2-10 mgKOH/g is preferred in pigment-based blending.

L'invention vise à fournir une encre pour jet d'encre qui présente une excellente aptitude à l'impression intermittente lorsqu'elle est utilisée pour une imprimante à jet d'encre de type à la demande, est peu susceptible de faible rendement d'impression lorsque l'impression est reprise, et est peu susceptible d'être floue ou éliminée, même lorsqu'elle est frottée de façon répétée avec le bout d'un doigt ou analogue après avoir été imprimée sur une surface métallique, une surface faiblement polaire, ou analogue. L'invention décrit une résine phénolique ayant un point de ramollissement de 70 à 125 °C, un agent poisseux, un agent colorant, et un solvant organique étant mélangés. Le solvant organique est de préférence un alcool ayant 1 à 3 atomes de carbone. Comme agent poisseux, une résine terpène phénolique ayant un indice d'hydroxyle de 10 à 45 mg de KOH/g est préférée dans le mélange à base de colorant, et une résine ester de colophane ayant un indice d'acide de 2 à 10 mg de KOH/g est préférée dans le mélange à base de pigment.

【課題】オンデマンド型のインクジェットプリンタに使用した際の間欠印刷性に優れ、印刷再開時に印字がかすれたりしにくい上、金属表面や低極性表面等に印刷後に指先等で繰り返しこすっても上記印字がかすれたり取れたりしにくいインクジェットインクを提供する。 【解決手段】軟化点が70~125℃であるフェノール樹脂、粘着付与剤、着色剤、および有機溶剤を配合した。有機溶剤としては炭素数1~3のアルコールが好ましい。また粘着付与剤として、染料系の配合では、水酸基価が10~45mgKOH/gのテルペンフェノール樹脂が好ましく、顔料系の配合では、酸価が2~10mgKOH/gのロジンエステル樹脂が好ましい。
