Title (EN) PHOTOCURABLE CLEAR INK COMPOSITION FOR INKJET PRINTING
(FR) COMPOSITION D'ENCRE CLAIR PHOTOCURCISSABLE POUR IMPRESSION À JET D'ENCRE
(JA) 光硬化型インキジェット印刷用クリアインキ組成物
Abstract:
(EN) The present invention addresses the problem in which microgelation caused by heat may easily occur in a clear ink so that storage stability of the ink may deteriorate, and when the microgelation occurs in the clear ink over time, the inkjet ejection property may deteriorate. To solve the problem, the present invention provides a clear ink composition for inkjet printing, in which a photopolymerizable compound, a photopolymerization initiator, and an inorganic filler having an average particle diameter of 1-200 nm are contained in an amount of 0.05-5.0 mass%, and which has a visible light transmittance of 30% or higher.
(FR) La présente invention vise à résoudre le problème selon lequel la microgélification provoquée par la chaleur peut facilement se produire dans une encre claire, pouvant entraîner la détérioration de la stabilité au stockage de l'encre et, lorsque la microgélification se produit dans l'encre claire au cours du temps, pouvant entraîner la détérioration de la propriété d'éjection de jet d'encre. La présente invention concerne par conséquent une composition d'encre claire pour l'impression par jet d'encre, dans laquelle un composé photopolymérisable, un initiateur de photopolymérisation, et une charge inorganique ayant un diamètre de particule moyen de 1 à 200 nm sont contenues en une quantité de 0,05 à 5,0 % en masse, et qui a une transmittance de lumière visible de 30 % ou plus.
(JA) クリアインキは熱によるミクロゲル化が起こりやすく、貯蔵安定性が低下する可能性があり、さらにクリアインキが経時でミクロゲルが発生するとインキジェット吐出性が低下する課題がある。解決方法として、光重合性化合物、光重合開始剤、及び平均粒径1~200nmの無機フィラーを組成物中0.05~5.0質量%含有し、可視光透過率が30%以上である光硬化型インキジェット印刷用クリアインキ組成物を提供する。
