<p>A UV ray curable ink comprising pigment, a polymerizable compound, and a photopolymerization initiator, wherein the UV ray curable ink has an absolute value of a viscosity difference between a viscosity at 25 {C at shear rate 10 (1/s) and a viscosity at 25 {C at shear rate 1000 (1/s) being not more than 5 mPa Ò s, and has a surface tension at 25 {C of from 26 to 38 mN/m. The polymerizable compound may be a cation polymerizable compound comprised of an oxetane compound and at least one of an epoxy compound and a vinyl ether compound. Also shown is an image formation method using the UV curable ink.</p> |
