ABSTRACT:
An aqueous dispersion of a vinylidene chloride resin which, when coated onto a synthetic resinous film substrate, has the combined properties of: (1) good adhesion to the substrate; (2) good adhesion of a printing ink to the coating; (3) satisfactory barrier to gases (especially oxygen) and water vapor; and (4) a high resistance to a boiling water treatment. The dispersion must also contain an unsaturated carboxylic acid in an amount of from about 0.5.times.10.sup.-4 to about 4.times.10.sup.-4 mol of unsaturated carboxylic acid units per gram of solids in the dispersion. The unsaturated carboxylic acid must have a partition coefficient of greater than or equal to 1. A limited portion of the amount of the unsaturated carboxylic acid is contained in the aqueous phase. The remaining unsaturated carboxylic acid is polymerized with the vinylidene chloride.
