PURPOSE: A non-solvent and UV-curable white ink composition is provided to prevent environmental contamination when applied to an optical film and to ensure excellent durability, a fast hardening rate, and yellowness. CONSTITUTION: A non-solvent and UV-curable white ink composition comprises an oligomer of which terminal is modified with an unsaturated group, photopolymerizable monomer, white pigment, and photopolymerization initiator and has reflectivity of 85% or more when the thickness after curing is 20 micron. The white ink composition further comprises at least one selected from a dispersing agent, leveling agent, and stabilizer. |
