Title:
ULTRAVIOLET CURABLE INK, METHOD FOR FORMING CURED PRODUCT, CURED PRODUCT, AND APPARATUS FOR FORMING CURED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/233770
Kind Code:
A1
Abstract:
The present invention relates to an ultraviolet curable ink which is capable of suppressing yellowing and a decrease in the luminance of a cured product formed therefrom, and which is also capable of suppressing a decrease in the curability of the cured product. The ultraviolet curable ink contains a photopolymerizable compound, a light-accumulating pigment which emits light having a wavelength of 405 nm, and a photopolymerization initiator which has an absorption coefficient of 100 mL/g∙cm or more for light having a wavelength of 405 nm; and the content of the photopolymerization initiator is 0.1% by mass to 1.5% by mass relative to the total mass of the photopolymerizable compound.
