Recording method, light curable type ink set, and recording apparatus

摘要

Provided is a recording method using a light-curable-type ink set including a light-curable-type color-ink composition containing a polymerizable compound, a photopolymerization initiator, and a coloring material and a light-curable-type clear-ink composition containing a polymerizable compound and a photopolymerization initiator, wherein the light-curable-type color-ink composition contains (1) an acylphosphine oxide-based photopolymerization initiator and (2) at least one of a thioxanthone-based photopolymerization initiator and/or an α aminoalkylphenone-based photopolymerization initiator which is in a range of 0.5 to 4 mass % with respect to the total mass of the color ink composition, wherein the light-curable-type clear-ink composition contains an acylphosphine oxide-based photopolymerization initiator which is in a range of 5 to 12 mass % with respect to the total mass of the clear-ink composition, and wherein illumination energy when a coated film made from the ink set is cured through light illumination from a light source is in a range of 100 to 800 mJ/cm2.

1. A recording method using a light curable type ink set including a light curable type color ink composition containing a polymerizable compound, a photopolymerization initiator, and a coloring material and a light curable type clear ink composition containing a polymerizable compound and a photopolymerization initiator,
wherein the light curable type color ink composition contains (1) an acylphosphine oxide-based photopolymerization initiator and (2) at least one of a thioxanthone-based photopolymerization initiator and/or an α amino alkyl phenone-based photopolymerization initiator which is in a range of 0.5 to 4 mass % with respect to the total mass of the color ink composition, wherein the light curable type clear ink composition contains an acylphosphine oxide-based photopolymerization initiator which is in a range of 5 to 12 mass % with respect to the total mass of the clear ink composition, wherein illumination energy at the time when a coated film made from the ink set is cured through light illumination from a light source is in a range of 100 to 800 mJ/cm2, and wherein a first coated film of the light curable type color ink composition is formed on the recording medium, and a second coated film of the light curable type clear ink composition is formed on the first coated film.
