Abstract:
(EN) Provided is a pigmented aqueous inkjet recording liquid with which clogging of a nozzle is improved and stable discharge is possible, with said aqueous inkjet recording liquid having excellent properties-in particular, an optical density (OD) value and wear resistance-which are required of an inkjet recording liquid. This aqueous inkjet recording liquid is a polymer emulsion which is obtained by using specific amounts of an emulsifier, water, and an aqueous polymerization initiator to radical-polymerize a radical-polymerizable unsaturated monomer (a), for which a radical-polymerizable unsaturated monomer (a2) having a specific amount of an alkoxysilyl group is an essential component; wherein said recording liquid contains a pigment and a polymer emulsion in which, according to the particle counting method, the number of 1.5 μm or larger ultra-coarse particles in the polymer emulsion when converted to a solid content concentration 0.1% is 5.0 × 105/cm3.
(FR) L'invention concerne un liquide d'impression à jet d'encre aqueux de type pigment, qui permet d'améliorer les problèmes d'obstruction de la buse et permet une éjection stable. Ce liquide d'impression à jet d'encre aqueux présente, en tant que liquide d'impression à jet d'encre, des propriétés physiques recherchées, notamment d'excellentes propriétés de valeur de densité optique (OD) et de résistance à l'usure. Ce liquide d'impression à jet d'encre aqueux consiste en une émulsion de polymère obtenue par polymérisation radicalaire, à l'aide d'un volume spécifique d'agent émulsifiant, d'eau et d'agent initiateur de polymérisation aqueux, d'un monomère insaturé à polymérisation radicalaire (a) comprenant obligatoirement un monomère insaturé à polymérisation radicalaire (a2) possédant un volume spécifique de groupe alcoxysilyle. Le liquide d'impression à jet d'encre aqueux comprend d'une part une émulsion de polymère dont, selon une méthode de comptage des particules, le nombre de particules très grossières supérieures ou égales à 1,5 μm, dans une émulsion de polymère mesurée avec une densité en matière solide de 0,1%, est inférieur ou égal à à 5,0x105 particules/cm3; il comprend d'autre part un pigment.
(JA)  本発明の目的は、ノズルでの目詰まりを改善して安定な吐出を与える顔料タイプの水性インクジェット記録液であって、インクジェット記録液として要求される物性、特にOD値、耐磨耗性に優れる水性インクジェット記録液を提供することにある。本発明に係る水性インクジェット記録液は、特定量のアルコキシシリル基を有するラジカル重合性不飽和モノマー(a2)を必須とするラジカル重合性不飽和モノマー(a)を、特定量の乳化剤、水及び水性重合開始剤を用いて、ラジカル重合してなるポリマーエマルションであって、個数カウント法では、固形分濃度0.1%換算におけるポリマーエマルション中の1.5μm以上の超粗大粒子数が5.0×105個/cm3以下のポリマーエマルション及び顔料を含有するものである。
