ABSTRACT:
The present invention is an infra red (IR)-blocking coating and a process for applying the IR-blocking coating onto the surface of a polymer. The process comprises the steps of dispersing an IR-blocking material in a mixture of solvent comprising a dissolved polymer and using standard printing processes to coat at least a portion of the surface of a bulk polymer, preferably a sheet or film. The present invention also provides safety glass laminates whose polymer interlayers have improved adhesion to glass in addition to light blocking properties.
