Beschreibung
Zusammenfassung:	A releasing primer composition contains at least one type selected from (1) to (3) below, for forming the releasing primer layer which is used in a laminate by lamination layered in the order of a resin base material, the releasing primer layer, a printed layer, and a sealant layer: (1) a mixture containing a silane coupling agent containing glycidyl groups and a polyethyleneimine compound; (2) a mixture containing a silane coupling agent containing isocyanate groups and a polyethyleneimine compound; (3) a siloxane-modified polyethyleneimine compound. The releasing primer composition is intended to allow the base material and the printed layer to adhere together strongly and unfailingly during use, while more easily separating/releasing the printed layer from the resin base material and from sealant layer, as well as to achieve excellent laminatability and post-retort laminatability.
