Title: INKJET INK AND INKJET IMAGE FORMATION METHOD USING SAME
Abstract:
Provided is an ultraviolet-light curable inkjet ink and an inkjet image formation method that uses said inkjet ink. The inkjet ink can be discharged from an inkjet head without being diluted by a solvent, has high photocuring sensitivity and produces high quality images with excellent weather resistance (smear resistance). The inkjet ink is characterised by a polymer compound that contains a compound selected from a chiral group containing maleimide compound, a vinyl ether compound and an N-vinyl compound, in an ultraviolet-light curable inkjet ink that contains at least the polymer compound.
