Zusammenfassung:	Provided is an ink composition that is obtained by using an ultraviolet-curable urethane acrylate resin together with a tungsten-based infrared-absorbing pigment and an ultraviolet-absorbing fluorescent pigment. Specifically, this infrared-absorbing ultraviolet-curable ink contains: a tungsten-based infrared-absorbing pigment; a UV-absorbing fluorescent pigment; a UV-curable urethane acrylate resin; and a UV-curable acrylic resin that does not contain a urethane bond. L'invention concerne une composition d'encre qui est obtenue en faisant appel à une résine d'uréthane acrylate durcissable aux ultraviolets conjointement avec un pigment absorbant les infrarouges à base de tungstène et un pigment fluorescent absorbant les ultraviolets. Plus précisément, cette encre durcissable aux ultraviolets absorbant les infrarouges contient : un pigment absorbant les infrarouges à base de tungstène ; un pigment fluorescent absorbant les UV ; une résine d'uréthane acrylate durcissable aux UV ; et une résine acrylique durcissable aux UV qui ne contient pas de liaison uréthane. 紫外線硬化型ウレタンアクリレート樹脂を、タングステン系赤外線吸収性顔料及び紫外線吸収性蛍光顔料とともに用いたインク組成物とする。具体的には、タングステン系赤外線吸収性顔料、紫外線吸収性蛍光顔料、紫外線硬化型ウレタンアクリレート樹脂、及びウレタン結合を含まない紫外線硬化型アクリル樹脂、を含む、赤外線吸収性紫外線硬化型インクとする。
