Claims19
An ink jet composition set comprising:
- a radiation-curable color composition, which contains a perinone-based pigment, a polymerizable compound and a polymerization initiator;
- and
- a radiation-curable clear composition, which contains an ultraviolet absorber, a polymerizable compound, and a polymerization initiator,
- wherein, at a concentration contained in the radiation-curable clear composition, a light absorbance of the ultraviolet absorber at a wavelength of 380 nm or more and 430 nm or less is smaller than a light absorbance of the polymerization initiator in the radiation-curable clear composition.
