Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
80 words
A COATING COMPOSITION COMPRISING A XYLENESOLUBLE, UNSATURATED POLYMERZATE SELECTED FROM THE GROUP CONSISTING OF HOMOPOLYMERS OF POLYOLEFINIC ESTERS OF 2-ALKENOLS AND 2-ALKENOXYALKANOLS, AND INTERPOLYMERS OF AT LEAST 20% BY WEIGHT OF SUCH POLYOLEFINIC ESTERS WITH A COPOLYMERIZABLE MONOOLEFINIC COMPOUND, IN ADMIXTURE WITH A FLUORIDE SALT SELECTED FROM THE GROUP CONSISTING OF AMMONIUM FLUORIDE AND AMMONIUM BIFLUORIDE, SAID FLUORIDE SALT BEING PRESENT IN AN AMOUNT WITHIN THE RANGE OF FROM ABOUT 0.05% TO 5.0% BY WEIGHT OF THE SAID POLYMERIC MATERIAL.
