[Object]To provide a recording method by which the occurrence of bleeding and repelling in a cured layer can be suppressed during overprinting.[Solution]In a recording method, a first ink composition containing a colorant, a photopolymerizable compound, and a photopolymerization initiator is ejected from a recording head onto a recording medium; light is emitted from a light source to the first ink composition that has adhered to the recording medium with the result that the first ink composition is cured at a cure rate that is in the range from 70 to 95%; a second ink composition containing a colorant, a photopolymerizable compound, and a photopolymerization initiator is ejected from a recording head to the first ink composition that has been cured on the recording medium; and light is emitted from a light source to the second ink composition.
摘要:
An ultraviolet hardenable ink composition excelling in the wetting characteristic (repellence prevention) of ink having impacted a recording medium. There is provided an ultraviolet hardenable ink composition characterized by containing a polyester-modified polydimethylsiloxane as a surfactant in an amount of 0.01 to 1% based on the ultraviolet hardenable ink. Preferably, at least allyl glycol and/or a N-vinyl compound is contained as a polymerizable compound. Incorporation of the polyester-modified polydimethylsiloxane in the surfactant has realized enhancing of the wetting characteristic on all nonabsorptive material surfaces and avoiding of ink repellence.
