Abstract:
An ultraviolet curable inkjet recording ink of the present invention includes at least a colorant, a light-curable compound, a photopolymerization initiator, and at least one fluorine surfactant represented by the following formulae (1) or (2) as a surface tension regulator: where Rf is selected from CH2CF3 and CH2CF2CF3; n represents a value of 5 to 20; and each R1 represents a functional group capable of initiating an ultraviolet curing reaction and one of the two R1s in (1) may be hydrogen; where Rf is selected from CH2CF3 and CH2CF2CF3; l represents a value of 1 to 20; k and m each represent a value of 1 to 8; each R2 represents a functional group capable of initiating an ultraviolet curing reaction and one of the two R2s in (2) may be hydrogen; and R3 is selected from hydrogen and methyl.
