Ultraviolet curable type ink-jet ink composition, recording method and recording apparatus using same
摘要：
Provided is a UV curable type ink-jet ink composition containing a monomer A which is expressed by the following general formula (I): CH2═CR1—COOR2—O—CH═CH—R3  (I) (in the formula, R1 is a hydrogen atom or methyl radical, R2 is a bivalent organic residue radical having a carbon number in a range of 2 to 20, and R3 is a hydrogen atom or a univalent organic residue radical having a carbon number in a range of 1 to 11), a compound B containing five or more (meth)acryloyl radicals per molecule, and a monofunctional (meth)acrylate C having an aromatic ring skeleton, wherein the monofunctional (meth)acrylate C which is in a range of 5 to 35 wt % with respect to the total weight of the ink composition is contained, wherein the compound B is in a range of 5 to 40 wt % with respect to the total weight of the ink composition, wherein the monomer A is in a range of 10 to 70 wt % with respect to the total weight of the ink composition.
摘要（中）：
