Laminate and method for its preparation
First Claim
1. A transparent laminate made of a transparent hard material having a soft synthetic resin layer on its surface, wherein the soft synthetic resin layer has, at its exposed surface side, a surface of a cross-linked polyurethane type resin having a self-healing property with the surface reformed by impregnating an additionpolymerizable unsaturated compound into the cross-linked polyurethane resin surface and polymerizing the impregnated compound.

Abstract
A transparent laminate made of a transparent hard material having a soft synthetic resin layer on its surface, wherein the soft synthetic resin layer has, at its exposed surface side, a surface of cross-linked polyurethane type resin having a self-healing property with the surface reformed by impregnating an addition-polymerizable unsaturated compound into the cross-linked polyurethane resin surface and polymerizing the impregnated compound.

- 1. A transparent laminate made of a transparent hard material having a soft synthetic resin layer on its surface, wherein the soft synthetic resin layer has, at its exposed surface side, a surface of a cross-linked polyurethane type resin having a self-healing property with the surface reformed by impregnating an additionpolymerizable unsaturated compound into the cross-linked polyurethane resin surface and polymerizing the impregnated compound.
- 17. A method for preparing a transparent laminate which comprises laminating a transparent hard material and a pre-laminated sheet including a soft synthetic resin layer, in which the pre-laminated sheet has, at its one side, a surface of an adhesive material layer and, at the other side, a surface of a cross-linked polyurethane type resin having a self-healing property with the surface reformed by the impregnation and polymerization of an addition-polymerizable unsaturated compound, and the pre-laminated sheet is laminated onto the transparent hard material with the surface of said adhesive material layer being the lamination surface.
- 32. A pre-laminated sheet of a cross-linked polyurethane type resin having, at one side, a surface reformed by the impregnation and polymerization of an addition-polymerizable unsaturated compound and having a self-healing property and, at the other side, a layer of an adhesive material.
- 46. A method for preparating a pre-laminated sheet which comprises forming a layer of an adhesive material on one side of a sheet of a cross-linked polyurethane type resin having a self-healing property, protecting the surface of the adhesive material layer with a removable protective film or sheet, and then impregnating an addition-polymerizable unsaturated compound into the exposed side of the cross-linked polyurethane resin sheet and polymerizing the impregnated compound.
