Claim 1
Independent Claim
92 words
AN ARTICLE OF MANUFACTURE COMPRISING (A) A LAYER OF A SOLID LINEAR POLYMERIC POLYESTER, SELF-SUSTAINING IN THIN FILM FORM, OF POLYBASIC ALIPHATIC ALCOHOL AND POLYCARBOXYLIC AROMATIC ACID; AND (B) A LAYER OF AN ORGANIC HYDROGEN-CONTAINING POLYMER HAVING A PLURALITY OF CARBON ATOMS IN THE SKELETAL CHAIN, SAID ARTICLE HAVING HIGH INTERFACIAL BONDING AT AN INTERFACE BETWEEN SAID LAYERS, SAID INTERFACE HAVING BEEN STRONGLY IRRADIATED WITH ULTRAVIOLET LIGHT FROM AN ARTIFICIAL SOURCE AT AN INTENSITY AND FOR A TIME SUFFICIENT TO PROVIDE EFFECTIVE BONDING OF THE INTERFACIAL SURFACES WITHOUT SUBSTANTIALLY DEGRADING THE POLYMER.
Claim 2
Independent Claim
64 words
THE METHOD WHICH COMPRISES (A) FORMING AN INTERFACE BETWEEN ORGANIC POLYMER LAYERS, ONE OF WHICH IS MORE TRANSMISSIVE TO ULTRAVIOLET LIGHT THAN THE OTHER, AND, (B) STRONGLY IRADIATING SAID INTERFACE WITH ULTRAVIOLET LIGHT FROM AN ARTIFICIAL SOURCE AT AN INTENSITY AND FOR A TIME SUFFICIENT TO PROVIDE EFFECTIVE BONDING OF THE SAID LAYERS TO ONE ANOTHER AT SAID INTERFACE WITHOUT SUBSTANTIALLY DEGRADING SAID POLYMERS.
