Abstract
An object is to obtain a laminate that allows a printed layer to be separated/released more easily from a resin base material or sealant layer using a release solution, while achieving excellent lamination-suitability. As a solution, a laminate comprising a resin base material, a releasing primer layer, a printed layer, a releasing primer layer and a sealant layer, being stacked in this order, is provided, wherein the releasing primer composition for forming the releasing primer layers contains a polyethyleneimine-based compound with an amine value of 5.0 to 25.0 mmol/g and/or polybutadiene-based compound.
Claims9
A laminate comprising a resin base material, a releasing primer layer, a printed layer, a releasing primer layer, and a sealant layer, being stacked in this order, wherein the releasing primer layer releases the resin base material from the laminate in a recycling process, and a releasing primer composition for forming the releasing primer layers contains a polyethyleneimine-based compound with an amine value of 5.0 to 25.0 mmol/g and/or polybutadiene-based compound.
