Title:
ULTRAVIOLET RAY-CURABLE INKJET INK SET AND METHOD FOR PRODUCING PRINTED MATTER
Document Type and Number:
WIPO Patent Application WO/2022/137635
Kind Code:
A1
Abstract:
Prvodied is an ultraviolet ray-curable inkjet inkset for a line head printer, the inkjet inkset including a lower layer ink that contains a polymerizable monomer having a specific structure and a specific photopolymerization initiator, and an upper layer ink that contains a polymerizable monomer having a specific structure and a specific photopolymerization initiator. One of the lower layer ink and the upper layer ink is a white ink and the other is a black ink. As a result of using this ultraviolet ray-curable inkjet ink set, it is possible to obtain good-quality printed matter in which, even in the case of high-speed printing, the adherence between a recording medium and an ink layer and between different ink layers is excellent and there is no occurrence of a curing crease or curling that could develop as time passes.
