Abstract
Laminates of a thickness of 0.2 mm to 20 mm consisting of a film made of thermoplastic of a thickness of 0.02 mm to 0.8 mm, a colored layer, the softening temperature of which is above that of the film made of thermoplastic (1), optionally a polyurethane layer which is tack-free at room temperature and a layer of thermoplastic of a thickness of 0.1 mm to 19 mm which in turn consists of one or more layers of plastic.
Claims4
A laminate having a thickness of 0.2 to 20 mm consisting of the following layers:
- 1. a thermoplastic film having a thickness of 0.02 to 0.8 mm;
- 2. a colored layer in contact with the thermoplastic layer 1;
- 3. optionally a polyurethane layer which is tack-free at room temperature;
- and
- 4. a thermoplastic layer having a thickness of 0.1 to 19 mm, consisting of one or more layers of plastic, in contact with the colored layer 2, or if present, the polyurethane layer 3,
- wherein the colored layer 2 has a softening temperature above that of thermoplastic layer 1.
