Ink jet recording method, pigment dispersion and actinic radiation curable type ink jet ink composition

An ink jet recording method comprising steps of;

• ejecting microscopic ink droplets, and
• curing the ink by actinic radiation,
• wherein the ink contains a pigment dispersion comprising a photopolymerizable compound and a pigment, and
• hydrophilicity δm of surface of the pigment is at most 22 cal1/2·cm−1/2, the pigment being subjected to a surface treatment so as to have hydrophilicity δm of at most 22 cal1/2·cm−1/2,
• in which the hydrophilicity δm is determined based on the following method,
• the pigment is floated on a predetermined amount of water (B ml), and while stirring, acetone is introduced through a burette of which tip is placed in the water so that acetone is not directly poured onto the pigment, amount of the acetone (A ml) required to sink the pigment is recorded, and
• δm is calculated based on the formula.
• δm=(A·δacetone+B·δwater)/(A+B)
• δacetone=9.75 cal1/2·cm−1/2
• δwater=23.43 cal1/2·cm−1/2
