Abstract

Provided is a glass plate substitute film having superior substitutability for glass plates due to having superior impact resistance and light weight compared with glass plates, as well as sufficient scratch-preventing property, blooming resistance and yellowing resistance. The glass plate substitute film of the present invention includes: a substrate layer; and one or a plurality of surface layers overlaid on one side or both two sides of the substrate layer, wherein the substrate layer contains as a principal component a polycarbonate having a constitutional unit derived from a dihydroxy compound represented by the following formula (1), and wherein the dihydroxy compound is an extract of a plant or a derivative thereof. At least one surface layer of the one or the plurality of surface layers preferably contains an active energy ray-curable resin as a principal component. The active energy ray-curable resin is preferably an ultraviolet ray-curable epoxy resin.

Claims (14)

1. A glass plate substitute film comprising:

a substrate layer; and

one or a plurality of surface layers overlaid on one side or both two sides of the substrate layer,

wherein the substrate layer comprises as a principal component a polycarbonate comprising a constitutional unit derived from a dihydroxy compound represented by formula (1):

and wherein

the dihydroxy compound is an extract of a plant or a derivative thereof,

the one or a plurality of surface layers comprise an active energy ray-curable resin as a principal component,

the glass plate substitute film is to be used in place of a glass plate, and an average thickness of the substrate layer is no less than 100 μm and no greater than 1,000 μm, and

the substrate layer comprises a wavy and fine modulated structure having fine undulations along one direction, on one side face or both two side faces.

2. The glass plate substitute film according to claim 1 , wherein the active energy ray-curable resin is an ultraviolet ray-curable epoxy resin.

3. The glass plate substitute film according to claim 1 , wherein the polycarbonate further comprises a constitutional unit derived from an aliphatic dihydroxy compound other than the dihydroxy compound represented by the formula (1).

4. The glass plate substitute film according to claim 1 , further comprising an electrically conductive layer which is provided between the substrate layer and the at least one surface layer of the one or the plurality of surface layers, and comprises an electrically conductive inorganic material as a principal component.

5. The glass plate substitute film according to claim 1 , which is for use as a front plate of a display device.

6. A display device comprising the glass plate substitute film according to claim 5 .
