Releasing primer composition and printed matter

Abstract

An object is to allow a base material and a printed layer to bond together securely during use, while also making it easier to release the printed layer from the base material after use and facilitating the separation/release of the printed layer from the release solution thereafter, as well as to, in a laminate comprising a base material film and a paper base material layered thereon via an adhesive layer, facilitate the separation/release of the adhesive layer from the base material film. As a solution, a releasing primer composition containing a polyethyleneimine-based compound with an amine value of 5.0 to 25.0 mmol/g and/or polybutadiene-based compound is provided, which is used, with respect to a printed matter formed in the order of a resin base material, a releasing primer layer, and a printed layer, for forming the releasing primer layer.
