Claims
- 1. A process which comprises contacting the surface of a metal with a substituted hydroxybenzene of formula ##STR3## wherein:
- R is an acyl group containing 7 to 30 carbon atoms.
- 2. The process of claim 1 wherein the substituted hydroxybenzene has the structure ##STR4## wherein:
- R.sup.1 is an alkyl group containing 7 to 22 carbon atoms.
- 3. The process of claim 1 wherein the substituted hydroxybenzene is 4-octadecanoylcatechol or 4-hexadecanoylcatechol.
- 4. The process of claim 1 wherein the substituted hydroxybenzene is applied to the metal surface as a solution in an organic solvent, as an aqueous emulsion of the substituted hydroxybenzene or as an aqueous emulsion of a solution of the substituted hydroxybenzene.
- 5. A process as claimed in claim 4 wherein the substituted hydroxybenzene is incorporated into a surface coating composition.
- 6. The process of claim 5 wherein the surface coating composition is a paint, lacquer or a resin.
- 7. The process of claim 6 wherein contacting is effected at a temperature of from 0 to 50.degree. C.
- 8. The process of claims 7 wherein the metal is iron, zinc, copper, tin or aluminium.
- 9. The process of claim 8 wherein the metal surface is a lightly rusted iron surface.
- 10. A surface coating composition comprising a substituted hydroxybenzene of the formula ##STR5## wherein:
- R is an acyl group containing 7 to 30 carbon atoms.
- 11. A metal having on at least one surface thereof a coating which is, or which contains, a substituted hydroxybenzene of the formula ##STR6## wherein: R is an acyl group containing from 7 to 30 carbon atoms.
