Abstract
Corrosion inhibiting coating compositions are prepared comprising combining a mixture (I) of (A) a non-Newtonian colloidal disperse system comprising an alkali or alkaline earth metal carbonate predispersed in a dispersing medium in the presence of at least one organic alkali or alkaline earth salt of a carboxylic or sulfonic acid and (B) an acidic ester of a phosphoric acid with (II) a hydrocarbon resin which is substantially insoluble in said mixture (I) at temperatures below about 60.degree. C. The ester is typically a mono- or diester such as that from reaction of an alcohol and/or alkyl-substituted phenol and phosphorus pentoxide.
