ULTRAVIOLET CURING TYPE INKJET INK FOR LIGHT GUIDE PLATE, AND LIGHT GUIDE PLATE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet curing type inkjet ink for a light guide plate, capable of making light supplied from a planar light-source device have a more natural color tone when forming reflective dots of the light guide plate used for the planar light-source device by inkjet printing.

SOLUTION: The ultraviolet curing type inkjet ink for a light guide plate comprising: a titanium dioxide particle; a photopolymerizable component containing a photopolymerizable monomer having hydroxyl groups; and a photopolymerization initiator. Here, the 50% cumulative particle diameter D50 of the titanium dioxide particles is in a range of 200 to 1,000 nm.
