Title (EN) CLEANING LIQUID FOR AQUEOUS INK
(FR) DÉTERGENT LIQUIDE POUR ENCRE AQUEUSE
(JA) 水系インク用の洗浄液
Abstract:
(EN) The present invention relates to a cleaning liquid for an aqueous ink including a pigment and a water-insoluble polymer. The cleaning liquid includes: an acetylene glycol (A) having an average number of added moles of ethylene oxide (EO) of 0-2 mol; at least one compound (B) selected from acetylene glycols having an average number of added moles of EO of 4 mol or higher, and polyethylene glycol alkyl ethers having alkyl groups with eight or more carbon atoms; a water-soluble organic solvent (C); and water. The water-soluble organic solvent (C) includes at least one water-soluble organic solvent having a boiling point of 90˚C or higher. The boiling point of the water-soluble organic solvent (C) is 250˚C or lower as a weighted average value. The water-soluble organic solvent (C) content is 20 mass% or lower. The present invention also relates to a production method for said cleaning liquid, and an aqueous ink cleaning method which uses said cleaning liquid.
(FR) L’invention concerne un détergent liquide pour encre aqueuse qui contient un pigment et un polymère insoluble dans l’eau. Ce détergent liquide comprend : un glycol acétylénique (A) de nombre moyen de moles ajoutés de EO compris entre 0 et 2 ; une sorte de composé (B) ou plus choisie parmi un glycol acétylénique de nombre moyen de moles ajoutés de EO supérieur ou égal à 4, et un polyéthylène glycol alkyle éther possédant un groupe alkyle de 8 atomes de carbone ou plus ; un solvant organique soluble dans l’eau (C) ; et une eau. Le solvant organique soluble dans l’eau (C) comprend au moins une sorte de solvant organique soluble dans l’eau de point d’ébullition supérieur ou égal à 90°C. Le point d’ébullition du solvant organique soluble dans l’eau (C) est inférieur ou égal à 250°C en valeur moyenne pondérée. La teneur en solvant organique soluble dans l’eau (C) est inférieure ou égale à 20% en masse. L’invention concerne également un procédé de fabrication de ce détergent liquide, et un procédé de nettoyage d’encre aqueuse mettant en œuvre ce détergent liquide.
(JA) 顔料と水不溶性ポリマーを含む水系インク用の洗浄液であって、該洗浄液が、EOの平均付加モル数が0~2モルのアセチレングリコール(A)と、EOの平均付加モル数が4モル以上のアセチレングリコール、及び炭素数が8以上のアルキル基を有するポリエチレングリコールアルキルエーテルから選ばれる1種以上の化合物(B)と、水溶性有機溶媒(C)と、水とを含有し、水溶性有機溶媒(C)が沸点90℃以上の水溶性有機溶媒を1種以上含有し、水溶性有機溶媒(C)の沸点が、加重平均値で250℃以下であり、水溶性有機溶媒(C)の含有量が20質量%以下である、洗浄液、その製造方法及び該洗浄液を用いた水系インクの洗浄方法に関する。
