Abstract
Provided is an ultraviolet curable inkjet ink and an inkjet image formation method that uses said inkjet ink. The inkjet ink can be ejected from an inkjet head without being diluted by a solvent, has high photo curing sensitivity and produces high quality images with excellent weather resistance (smear resistance). The inkjet ink is characterized by a polymerizable compound which contains a maleimide compound having a chiral group and a compound selected from a vinyl ether compound and a N-vinyl compound.
Claims7
An ultraviolet curable inkjet ink comprising at least a polymerizable compound, wherein the polymerizable compound contains a maleimide compound having a chiral group and a vinyl ether compound, and wherein the maleimide compound has an asymmetric (chiral) carbon atom located at the first or the second position from a nitrogen atom of the maleimide.
