Photo-curable ink jet ink set and ink jet recording method using the same

An ink jet recording method using a photo-curable ink jet ink set comprising a first photo-curable ink jet ink and a second photo-curable ink jet ink, the method comprising:

• ejecting the first photo-curable ink jet ink onto a recording medium, the first photo-curable ink jet ink comprising a white ink;
• ejecting the second photo-curable ink jet ink onto the first photo-curable ink jet ink ejected onto the recording medium, wherein the second photo-curable ink jet ink comprises a non-white, color ink;
• and
• curing the first photo-curable ink jet ink and the second photo-curable ink jet ink;
• the curing being conducted using a UV-LED having an emission peak at a wavelength in the range of 350 to 420 nm;
• wherein the first photo-curable ink jet ink has a surface tension and contains a (meth) acrylic acid ester having a vinyl ether group expressed by general formula (I):
• CH2═CR1—COOR2—O—CH═CH—R3, wherein R1 represents a hydrogen atom or a methyl group, R2 represents a divalent organic residue having a carbon number of 2 to 20, and R3 represents a hydrogen atom or a monovalent organic residue having a carbon number of 1 to 11;
• and the second photo-curable ink jet ink has a surface tension,
• wherein the surface tension of the first photo-curable ink jet ink is higher than the surface tension of the second photo-curable ink jet ink.
