Abstract
In one form, the present invention provides a synthetic resin leather adhering a base material via an adhesive layer to the back side of a film composed mostly of thermoplastic polyurethane, and the film has on the surface thereof a surface treatment layer formed by coating with a surface treatment agent in which aqueous polycarbonate polyurethane is cross linked by aqueous cross-linking agent containing a carbodiimide group.
Claims4
A vehicle interior material comprising a synthetic resin leather including a base material adhered via an adhesive layer to a back side of a film composed of thermoplastic polyurethane, wherein a front side of the film has a surface treatment layer formed on a surface thereof, and the surface treatment layer is formed by coating the surface of the front side of film with a surface treatment agent in which an aqueous polycarbonate polyurethane is cross linked by an aqueous cross-linking agent containing a carbodiimide group to form the vehicle interior material.
A method of manufacturing a synthetic resin leather for use as a vehicle interior material, the method comprising the steps of:
- forming a film formed of thermoplastic polyurethane;
- forming a surface treatment layer on the surface of the front side of the film by coating the surface of the front side of the film with a surface treatment agent in which an aqueous polycarbonate polyurethane is cross linked by an aqueous cross-linking agent containing a carbodiimide group;
- and
- adhering a base material via an adhesive layer to the back side of the film to form the vehicle interior material.
