WIPO Patent Application WO/2023/054418
Kind Code:
A1
Abstract:
The present invention addresses the problem of making it possible to bond a print layer to a base material securely when the invention is used, and also makes it possible, after the invention is used, to more easily separate/detach the print layer from the base material, and subsequently to readily separate/detach the print layer from a detachment liquid. The present invention also addresses the problem of making it easy to separate/detach an adhesive layer from a base material film of a laminated body in which a paper base material is laminated on the base material film via the adhesive layer. Provided, as a solution to the problem, is a detachment primer composition for forming a detachment primer layer of a printed article comprising a resin base material, the detachment primer layer, and the print layer, in this order. The detachment primer composition contains a polyethyleneimine compound and/or a polybutadiene compound having an amine value of 5.0-25.0 mmol/g.
