1417403 Coated materials IMPERIAL CHEMICAL INDUSTRIES Ltd 1 June 1973 [22 June 1972] 29335/72 Heading B2E [Also in Division Cl] Materials are coated with a liquid composition containing a solution of Al and Ti compounds in a solvent, the ratio of Al:Li being in the range 20:1 to 1:20 by weight of the metals, the solution also containing phosphate in an amount such that there is present at least one atom of P per 20 atoms of total metal. After coating with the liquid composition the material is preferably heated to 100-600‹C, and the coating may be applied by spray-, dip-, roller- or bush coating. Examples of suitable Al and Ti compounds are halides, carboxylates, alkoxides, acetylacetonates, complex phosphates, halophosphate and complex nitrate phosphates and solvents used as alcohols, ethers, esters, ketones and alkoxy-alcohols. The coating is useful, for example, for reducing the corrosion of an U.V. light transmission onto the material.
