Summary: | To provide a pigment dispersion liquid used for preparing a UV-curable inkjet ink, which uses a yellow pigment or an orange pigment but yet allows these pigments to be dispersed suitably and stored stably.SOLUTION: The present invention provides a pigment dispersion liquid used for preparing a UV-curable inkjet ink, which comprises a pigment comprising at least either a yellow pigment or an orange pigment, a pigment derivative, an aminated polymer dispersant, and a UV-curable monomer. The pigment derivative has a structure represented by the general formula (1) (where X is OH or OCH3, and at least two of four X are OH).SELECTED DRAWING: None
【課題】イエロー顔料やオレンジ顔料を用いながらも、これらの顔料の分散性及び保存安定性に優れた、紫外線硬化型インクジェットインクを調製するために用いられる顔料分散液を提供する。【解決手段】イエロー顔料及びオレンジ顔料の少なくともいずれかを含む顔料、顔料誘導体、アミノ基を有する高分子分散剤、及び紫外線硬化性モノマーを含有する、紫外線硬化型インクジェットインクに用いられる顔料分散液である。顔料誘導体が、下記一般式(1)(一般式(1)中、XはOH又はOCH3を示し、4つのXのうち2以上がOHである)で表される構造を有する。TIFF2023058215000014.tif49170【選択図】なし |
