Abstract

Embodiments of the invention relate to an actinic-ray-curable resin composition which includes 100 parts by mass of a polyfunctional (meth)acrylate; 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; 0.05-3 parts by mass of an organic titanium; and 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm. Embodiments of the invention also relate to a layered transparent resin product which includes a hardcoat layer and a layer of a transparent resin sheet in this order from the outermost layer side, wherein the hardcoat has been formed from a coating material including 100 parts by mass of a polyfunctional (meth)acrylate; 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; 0.05-3 parts by mass of an organic titanium; and 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm.

First claim

The invention claimed is:

0.05 to 3 parts by mass of an organotitanium; and
5 to 100 parts by mass of microparticles comprising an average particle diameter of 1 to 300 nm; and
0.01 to 7 parts by mass of a water repellant.

2. The active energy ray-curable resin composition according to claim 1 , wherein the water repellant comprises a (meth)acryloyl group-containing fluoropolyether water repellant.

3. A hard coat-laminated film, comprising:
a transparent resin film; and
a hard coat formed on at least one surface of the transparent resin film from a coating material comprising the active energy ray-curable resin composition according to claim 1 .

4. A hard coat-laminated film, comprising:
a first hard coat layer;
a transparent resin film layer; and
a second hard coat layer, in order from the outermost surface layer side,
wherein the first hard coat layer is formed from a coating material comprising the active energy ray-curable resin composition according to claim 1 .

5. The hard coat-laminated film according to claim 3 , wherein the transparent resin film is a poly(meth)acrylimide resin film.

6. The hard coat-laminated film according to claim 5 , wherein the poly(meth)acrylimide resin film is a transparent multilayer film comprising:
a first poly(meth)acrylimide resin layer (α1);
an aromatic polycarbonate resin layer (β); and
a second poly(meth)acrylimide resin layer (α2),

directly laminated in this order.

7. A method for producing a hard coat-laminated film for a touch panel display face plate comprising a step of applying a coating material, for forming a hard coat, comprising an active energy ray-curable resin composition comprising:
100 parts by mass of a polyfunctional (meth)acrylate;
0.2 to 4 parts by mass of a compound comprising an alkoxysilyl group and a (meth)acryloyl group;

8. The method according to claim 7 , wherein the water repellant comprises a (meth)acryloyl group-containing fluoropolyether water repellant.

9. An image display apparatus member, comprising the hard coat-laminated film according to claim 3 .

10. A transparent resin laminate, comprising:
a layer of a hard coat and a layer of a transparent resin sheet, in order from the outermost surface layer side, wherein the hard coat is formed from a coating material comprising:
100 parts by mass of a polyfunctional (meth)acrylate;
0.2 to 4 parts by mass of a compound comprising an alkoxysilyl group and a (meth)acryloyl group;
0.05 to 3 parts by mass of an organotitanium;
5 to 100 parts by mass of microparticles comprising an average particle diameter of 1 to 300 nm; and 0.01 to 7 parts by mass of a water repellant.

11. The transparent resin laminate according to claim 10 , wherein the transparent resin sheet is a poly(meth)acrylimide resin sheet.

12. The transparent resin laminate according to claim 11 , wherein the poly(meth)acrylimide resin sheet is a laminated sheet comprising:
a first poly(meth)acrylimide resin layer;
an aromatic polycarbonate resin layer; and
a second poly(meth)acrylimide resin layer,

directly laminated in this order.

13. A vehicle member, comprising the transparent resin laminate according to claim 10 .
