Title
(EN) DISPERSION, INK COMPOSITION, AND PRINTED ARTICLE
(FR) DISPERSION, COMPOSITION D'ENCRE ET ARTICLE IMPRIMÉ
(JA) 分散液、インク組成物、及び印刷物
Abstract
(EN) Provided is a dispersion that, even when used in an ink composition for ejection via an inkjet method, prevents the loss of phosphor luminescence and enables the manufacture of an ink composition with high ejection stability. The dispersion is used in an ink composition for ejection via an inkjet method, and a fluorescent complex containing a rare earth metal element is dispersed in the dispersion. The median diameter D50 of the fluorescent complex is preferably 5 μm or less.
(FR) L'invention concerne une dispersion qui, même lorsqu'elle est utilisée dans une composition d'encre pour éjection par l'intermédiaire d'un procédé à jet d'encre, empêche la perte de luminescence de luminophore et permet la fabrication d'une composition d'encre ayant une stabilité d'éjection élevée. La dispersion est utilisée dans une composition d'encre pour éjection par l'intermédiaire d'un procédé à jet d'encre, et un complexe fluorescent contenant un élément de métal des terres rares est dispersé dans la dispersion. Le diamètre médian D50 du complexe fluorescent est de préférence inférieur ou égal à 5 µm.
(JA) インクジェット方式によって吐出されるインク組成物に用いられる分散液であっても、蛍光体の発光性が失われることを抑制するとともに、吐出安定性の高いインク組成物を製造可能な分散液を提供する。 インクジェット方式によって吐出されるインク組成物に用いられる分散液であって、希土類金属元素を含有する蛍光発光錯体が前記分散液中に分散されている分散液である。蛍光発光錯体のメディアン径D50が5μm以下であることが好ましい。
