The purpose of the present invention is to provide an actinic ray curable inkjet ink which, in an inkjet printing method, is capable of having both high pinning characteristics and high ejection characteristics. In order to achieve the above purpose, this actinic ray curable inkjet ink includes an actinic ray curable compound, ketone wax, and ester wax, and reversibly goes through a sol-gel phase transition depending on the temperature.
A resin composition comprising:
a polymer (1) whose enthalpy of fusion (ΔH) observed within a temperature range of 10°C or higher and lower than 60°C in differential scanning calorimetry is 30 J/g or more; and
a low-molecular-weight compound (3) whose enthalpy of fusion (ΔH) observed within a temperature range of 0°C or higher and lower than 100°C in differential scanning calorimetry is 30 J/g or more and whose molecular weight is 2000 or lower, wherein
a content of the low-molecular-weight compound (3) is 3 parts by weight or more and 1000 parts by weight or less, with respect to 100 parts by weight of the total amount of polymer components contained in the resin composition except the low-molecular-weight compound (3) which is a polymer.
