Patent ID: 7264330

Claim:
A process for preparing an ink jet printed matter, comprising the steps of: heating an ink composition to between 40° and 150° C., said ink composition comprising a coloring component, a reactive diluent, a photoinitiator, and a reactive oligomer and/or a reactive prepolymer, wherein a polymer of said reactive oligomer and/or a polymer of said reactive prepolymer has a glass transition point between 0° and 70° C., and a polymer of said reactive diluent has a glass transition point between 0° and 70° C. and the difference in the glass transition point of said polymer of said reactive oligomer and/or reactive prepolymer and said polymer of said reactive diluent is at most 30° C., discharging the heated ink composition from a printer head to a recording medium comprising a flexible material, and curing the ink composition on the recording medium by irradiating with ultraviolet ray.
