Abstract

Provided is a hard coat film which has an inorganic hard coat layer having excellent scratch resistance and weatherability and inhibited from generation of curling and which is particularly suited for sticking on outside faces of window glasses in lofty buildings. The hard coat film is prepared by laminating in order a primer layer and a hard coat layer comprising metal oxide particles and a cured matter of a silane compound on one face of a base material and further providing, if necessary, a coating layer having various functions on the above hard coat layer.

Claims

1. A hard coat film which comprises a laminate wherein a primer layer and a hard coat layer comprising metal oxide particles and a cured matter of a silane compound are laminated in order on one face of a base material.

2. The hard coat film as described in claim 1, wherein a coating layer is further provided on the hard coat layer.

3. The hard coat film as described in claim 2, wherein the coating layer is a layer having at least one function selected from a photocatalytic function, an infrared ray-shielding function, a UV ray-shielding function, an antibacterial function, a contamination preventing function, an antistatic function, a color developing function and a cloudiness preventing function.

4. The hard coat film as described in claim 3, wherein the coating layer is a photocatalytic function layer, and the base material comprises polycarbonate.

5. The hard coat film as described in any of claims 1 to 4, wherein an adhesive layer is provided on the other face of the base material.
