Document Type and Number:
WIPO Patent Application WO/2022/004524
Kind Code:
A1
Abstract:
Provided are: an infrared ray-absorbing ultraviolet-ray curable ink which has infrared ray-absorbing ability and from which it is possible to provide printed matter having excellent resistance to bases, particularly resistance to washing; and an infrared ray-absorbing printed matter. According to the present invention, an ink composition is obtained by using an ultraviolet-ray curable urethane acrylate resin together with a tungsten-based infrared ray-absorbing pigment. More specifically, this infrared ray-absorbing ultraviolet-ray curable ink contains a tungsten-based infrared ray-absorbing pigment, an ultraviolet-ray curable urethane acrylate resin, and an ultraviolet-ray curable acrylic resin not including a urethane bond.
