ABSTRACT:
An organic polymer article has a surface coating of a metal phosphate. The coating has a thickness in the range of 0.01 to 5 microns; preferably, the metal phosphate comprises a mixture of iron and titanium orthophosphate, although the metal may be chosen from the elements of a periodic table having an atomic number of 12, 14, 20 to 32, 39 to 50, 56 to 80, 90 or 92. A continuous coating of the metal phosphate is obtained by applying to the organic polymer article a solution of a compound of the metal wherein the solution contains an organic component. The solution is converted to the coating of the metal phosphate by drying.
