Process for permanently cladding an inorganic surface with plastic and product made thereby

Claim 1

A PROCESS FOR PERMANENTLY CLADDING AN INORGANIC SURFACE WITH PLASTIC WHICH COMPRISES INTIMATELY CONTACTING (1) AN INORGANIC SURFACE PRIMED WITH AN ORGANIC MATERIAL CONTAINING ULTRAVIOLET LIGHT SENSITIVE GROUPS WHICH ARE ACTIVATED BY ULTRAVIOLET LIGHT IN WAVELENGTHS OF BETWEEN ABOUT 2000 A. 3600 A. WITH (2) A THERMOPLASTIC POLYMER CLADDING LAYER, SAID POLYMER BEING SELECTED FROM THE GROUP CONSISTING ESSENTIALLY OF CARBON AND HYDROGEN, CARBON AND HALOGENS WHEREIN AT LEAST SOME OF THE HALOGENS ARE OTHER THAN FLUORINE, AND COMBINATIONS OF CARBONS WITH HYDROGEN AND HALOGEN, AND (3) SUBJECTING THE LAMINATE SO FORMED TO ULTRAVIOLET IRRADIATION OF WAVELENGTHS IN THE RANGE OF ABOUT 2000 A. TO 3600 A. WHILE MAINTANING INTIMATE CONTACT AT THE INTERFACE BETWEEN THE PRIMED INORGANIC SURFACE AND THE CLADDING LAYER AND AT A TEMPERATURE BETWEEN ABOUT 100*C. AND 200*C. FOR A PERIOD OF TIME SUFFICIENT TO PERMANENTLY ADHEARE SAID CLADDING LAYER AND SAID PRIMED INORGANIC SURFACE TO ONE ANOTHER.
