Abstract
There is provided a composition suitable for use as a coating composition which contains a halogen-containing complex phosphate of aluminum, other than a phosphate ester, dissolved in an organic solvent. The complex contains at least one chemically-bound molecule of an alcohol having from one to 10 carbon atoms. The complex is prepared by interacting an aluminum compound, such as aluminum halides, with an alcohol containing one to 10 carbon atoms and with phosphoric acid.
Claims8
A composition suitable for use as a coating composition comprising a halogen-containing complex phosphate of aluminium other than a phosphate ester dissolved in an organic solvent, in which the complex contains at least one chemically-bound molecule of an alcohol containing from one to 10 carbon atoms and in which the complex has been prepared by interacting an aluminium compound selected from the group consisting essentially of aluminium halides, aluminium oxyhalides, aluminium alkoxyhalides and aluminium alkoxides with an alcohol containing one to 10 carbon atoms and with phosphoric acid, and when the aluminium compound is an alkoxide, with a halogen acid.
