The present invention relates to a printing method, a printing apparatus, and a printed document by which an ink offset can be prevented while securing a sufficient adhesion force of the pressure-sensitive adhesive layer. Ink is applied so that, when ink applied to a pressure-sensitive adhesive layer of a pressure-sensitive adhesive sheet cures, a convex section of the pressure-sensitive adhesive layer exposed out of the curried ink, thereby printing an image.

Printing method, printing apparatus, and printed document

An useful aqueous photocurable resin composition is provided. The aqueous photocurable resin composition of the present invention comprises at least water, a polymerizable material polymerizable with radical initiation and a water-soluble photopolymerization initiator which generates a radical with light, wherein the polymerizable material has at least two polymerizable functional groups and one anionic functional group.
