PROBLEM TO BE SOLVED: To provide an ultraviolet ray-curable ink composition having a small degree of initial pigmentation, excellent curability of an ink and excellent scratch resistance of a cured film, and a recording method using the composition.SOLUTION: The ultraviolet ray-curable ink composition comprises a polymerizable compound and a photopolymerization initiator. The polymerizable compound contains a monomer A represented by general formula (1): CH=CR-COOR-O-CH=CH-Rby 40 to 90 mass% with respect to the total amount of the ink composition (in the formula, Rrepresents a hydrogen atom or a methyl group; Rrepresents a divalent organic residue having 2 to 20 carbon atoms; and Rrepresents a hydrogen atom or a monovalent organic residue having 1 to 11 carbon atoms). The photopolymerization initiator contains acylphosphine oxide by 7 to 12 mass% with respect to the total amount of the ink composition, and the acylphosphine oxide contains monoacyl phosphine oxide.SELECTED DRAWING: None |
