Abstract
Provided are an ink set and a printed article, the ink set comprising an ink jet ink A which contains a polymerizable compound, a photopolymerization initiator, and perylene black and in which a proportion of a polyfunctional polymerizable monomer in the contained polymerizable compound is 60% by mass or more, and an ink jet ink B which contains a polymerizable compound, a photopolymerization initiator, and an infrared absorbing dye and in which a proportion of a polyfunctional polymerizable monomer in the contained polymerizable compound is 60% by mass or more.

An ink set comprising:
- an ink jet ink A which contains a polymerizable compound, a photopolymerization initiator, and perylene black and in which a proportion of a polyfunctional polymerizable monomer in the contained polymerizable compound is 60% by mass or more;
- and
- an ink jet ink B which contains a polymerizable compound, a photopolymerization initiator, and an infrared absorbing dye and in which a proportion of a polyfunctional polymerizable monomer in the contained polymerizable compound is 60% by mass or more.
A printed article comprising:
- a substrate;
- and
- a composite image that is disposed on the substrate and includes a black image and an infrared absorbing image including an overlap portion where the black image and the infrared absorbing image overlap each other in a plane view,
- wherein the black image is a cured substance of an ink jet ink A which contains a polymerizable compound, a photopolymerization initiator, and perylene black and in which a proportion of a polyfunctional polymerizable monomer in the contained polymerizable compound is 60% by mass or more, and
- the infrared absorbing image is a cured substance of an ink jet ink B which contains a polymerizable compound, a photopolymerization initiator, and an infrared absorbing dye and in which a proportion of a polyfunctional polymerizable monomer in the contained polymerizable compound is 60% by mass or more.
