The coating composition comprises a dispersion of barium sulphate in an aqueous solution of a water-soluble inorganic binder selected from the group consisting of alkali metal sulphates, ammonium sulphate and mixtures thereof. The coating is preferably employed in conjunction with an alkaline primer.
