Abstract

A lamination film for an electronic device, having excellent gas-barrier properties (e.g., barrier properties against water vapor), is provided.

A lamination film 20 comprises, in sequence: a base film 25 comprising a transparent polymer; an anchor layer 24 formed on a first side of the base film, the anchor layer comprising a cured product of a polymerizable composition containing a vinyl monomer and/or prepolymer; a barrier layer 23 comprising a metal or a metal compound; an etching protection layer 22 having an acid resistance or an alkali resistance; and a transparent electroconductive layer 21 comprising an inorganic compound. The vinyl monomer and/or prepolymer contains at least a silicone (meth)acrylate monomer and/or prepolymer. The lamination film 20 may comprise an anti-glare layer 26 formed on a second side of the base film. The lamination film 20 is disposed at a display side with respect to an ink layer of an electronic paper.

Claims

1-14. -14. (canceled)

15. A lamination film for an electronic device, the film comprising, in the following order:

a base film comprising a transparent polymer,

an anchor layer formed on at least a first side of the base film, the anchor layer comprising a cured product of a polymerizable composition containing at least one vinyl component selected from the group consisting of a vinyl monomer and a vinyl prepolymer,

a barrier layer comprising a metal or a metal compound,

an etching protection layer having an acid resistance or an alkali resistance, and

a transparent electroconductive layer comprising an electroconductive inorganic compound,

wherein the vinyl component contains at least one a first component selected from the group consisting of a silicone (meth)acrylate monomer and a silicone (meth)acrylate prepolymer.

16. A lamination film according to claim 15, wherein the vinyl component comprises:

at least one first component selected from the group consisting of a silicone (meth)acrylate monomer and a silicone (meth)acrylate prepolymer and

at least one second component selected from the group consisting of a silicon-free vinyl monomer and a silicon-free vinyl prepolymer,

wherein the second vinyl component comprises a urethane (meth)acrylate.

17. A lamination film according to claim 16, wherein the weight ratio of the first vinyl component relative to the second vinyl component is 1/99 to 30/70 as a ratio of the former/the latter.

18. A lamination film according to claim 15, wherein the barrier layer is formed by a film-forming means selected from the group consisting of a vacuum deposition, an ion plating, a sputtering, and a chemical vapor deposition, and the barrier layer has a thickness of 20 to 300 nm;

the etching protection layer comprises a cured product of a (meth)acrylic polymerizable composition, a silicon carbide, a fluorine carbide, or a titanium oxide; and

the electroconductive inorganic compound is a metal oxide.

19. A lamination film according to claim 15, which further comprises a functional layer formed on a second side of the base film.

20. A lamination film according to claim 19, wherein the functional layer is an anti-glare layer, and the anti-glare layer comprises one or a plurality of polymers and one or a plurality of cured products of curable resin-precursors, and has a phase-separation structure forming an uneven surface thereof.

21. A lamination film according to claim 15, which is a film for disposing at a viewing side of an electronic device.

22. A process for producing a lamination film recited in claim 15, which comprises forming an anchor layer on at least a first side of a base film by coating, and forming a barrier layer, an etching protection layer, and a transparent electroconductive layer in this order by physical or chemical vapor deposition.

23. A process according to claim 22, which comprises rolling up the film.

24. An electronic device provided with a lamination film recited in claim 15.
