Beschreibung
Zusammenfassung:	This photocurable inkjet ink contains a radical polymerizable compound, a photoinitiator, and a thixotropic agent, has a first viscosity of 1000 mPa∙s or less when measured at a shear rate of 10000 s-1, and has a second viscosity of 10000 mPa∙s or more when measured at a shear rate of 10-1 s-1 after continuously applying a shear force at a shear rate of 10000 s-1 for 30 seconds. L'invention concerne une encre photodurcissable pour jet d'encre qui contient un composé polymérisable par voie radicalaire, un photoinitiateur et un agent thixotrope, et qui possède une première viscosité inférieure ou égale à 1 000 mPa ∙ s lorsqu'elle est mesurée à une vitesse de cisaillement de 10 000 s-1, et possède une seconde viscosité supérieure ou égale à 10 000 mPa ∙ s lorsqu'elle est mesurée à une vitesse cisaillement de 10-1 s-1 après application continue d'une force de cisaillement à une vitesse de cisaillement de 10 000 s-1 pendant 30 secondes. 光硬化性吐出用インクは、ラジカル重合性化合物と、光開始剤と、チキソ剤とを含有し、剪断速度１００００ｓ-1で測定した第１の粘度が１０００ｍＰａ・ｓ以下であり、剪断速度１００００ｓ-1で剪断力を３０秒間加え続けた後に、剪断速度を１０-1ｓ-1とした状態で測定した第２の粘度が１００００ｍＰａ・ｓ以上である。
