Abstract:
1. A process for producing a molded printed material comprising: (A) a step of forming an image on a support by an inkjet method using an inkjet ink composition comprising a monofunctional radically polymerizable monomer, a colorant, and a polymerization initiator; (B) a step of forming a surface coating layer on the image by an inkjet method using an inkjet liquid composition comprising (1) at least one acrylate having a cyclic structure, and (2) a polymerization initiator, and comprising no colorant; (C) a step of curing the image by irradiation with actinic radiation; (D) a step of curing the surface coating layer by irradiation with actinic radiation so as to obtain a printed material having the image and the surface coating layer cured on the support; and (E) a step of molding the printed material, wherein the inkjet ink composition and the inkjet liquid composition are both radically polymerizable compositions, the radically polymerizable composition comprises a monofunctional radically polymerizable monomer containing only one ethylenically unsaturated double bond group selected from the group consisting of an acrylate group, a methacrylate group, an acrylamide group, a methacrylamide group, and an N-vinyl group, the content of the monofunctional radically polymerizable monomer in the radically polymerizable composition is at least 65 wt %, the inkjet ink composition comprises N-vinylcaprolactam as the monofunctional radically polymerizable monomer, the molding is embossing, vacuum forming, pressure forming, or vacuum/pressure forming, and both the inkjet ink composition and the inkjet liquid composition have a viscosity at 25° C. of no more than 50 mPa·s.
