Abstract

The present invention provides an active radiation curable ink composition including: (A) a polymer having two or more acidic groups or two or more basic groups; (B) a polymerizable monomer having a substituent group capable of forming a counter salt with the acidic group or basic group of the polymer (A); (C) a photo-polymerization initiator; and (D) a polymerizable monomer having a different structure from the polymerizable monomer (B).

Description

technical field [0001] The present invention relates to an active radiation curable ink composition, an ink composition for inkjet recording, a printed matter, and a method for producing a molded article of the printed matter. Background technique [0002] Various methods such as electrophotography, sublimation-type thermal transfer, fusion-type thermal transfer, and inkjet methods are called image recording methods in which an image is formed on a recording medium such as paper based on an image data signal. For example, the inkjet method is an excellent image recording method because it can be performed with inexpensive equipment, it uses ink efficiently and enables low running costs, because an image is printed on a recording medium by ejecting ink droplets only on the area where the image is formed. Formed directly, and it is less noisy. [0003] The inkjet method enables printing not only on plain paper but also on non-absorbent recording media such as plastic sheets a...
