Matte Film Having A Printable Polyalkylimine Condensation Product

摘要

Disclosed herein is a multi-layered matte film comprising at last one layer of a coating comprising the condensation reaction product of the combination of a polyalkylimine and an acetoacetonate (“AcAc”)-functional material or an oxirane-functional material, each comprising an ethenic unsaturation group, the coating adhered to a sealant film layer; a sealant layer comprising a polyolefin and having a Tm, within the range of from 120° C. to 170° C.; and a Flexural Modulus within the range from 500 to 1200 MPa; a core polypropylene layer; and a matte layer between the sealant layer and core layer, the matte layer comprising a blend of at least two incompatible polymers such that the Haze is at least 50%.

主权项

1. A multi-layered matte film having a first and second side, comprising a coating on at least the first side, wherein the coating comprises a condensation product of a polyalkylimine and one or more amine-reactive molecules comprising at least one of:
Rc═C(Ra)—(CX2)j—C(O)—(CX2)k—(O—[CRd2]q)p-A-C(O)—C(Rb)═CX2 or Y—(CX2)m—(O—[CRd2]q)p-A-C(O)—C(Rb)═CX2 where Y is halogen or a three-membered oxirane ring; Ra and Rb are the same or different and are H or a C1 to C6 to alkyl; Rc is oxygen or CX2; each X can be the same or different and is H, hydroxyl, halogen, or any organic radical containing at least one carbon atom, wherein each Rd can be the same or different and are H or a C1 to C6 to alkyl; A is oxygen or NRd; CRd and CRd2 can each be a separate moiety or a portion of a cyclic structure; j, k, and m are integers ranging from 0 to 6, inclusive; q is an integer ranging from 1 to 6, inclusive; and p is an integer ranging from 0 to 30, inclusive; wherein the multi-layer matte film comprises at least a core layer of polypropylene, a sealant layer comprising the first side, and a matte layer between the sealant layer and core layer.
