Abstract An adherable surface coating composition consisting essentially of an aqueous latex dispersion of (A) a water dispersible polyvinyl acetate composition having a molecular weight between about 20,000 and 250,000, having a cold flow test value of from about 20 to 2,000, and having a particle size range from about 0.1 to 25 microns, containing from about 0 percent to about 15 percent by weight, based on the weight of the polyvinyl acetate composition solids of a plasticizer, (B) from about 1 percent to about 10 percent, by weight, based on the weight of the polyvinyl acetate composition solids, of a protective colloid for (A), and (C) from about 0.1 percent to about 3 percent, by weight, based on the total weight of the dispersion of a water soluble starch and decorative laminates coated on their back sides with said coating composition.
A decorative laminate according to claim 1 wherein the core sheet is coated on its exposed surface with said adherable coating composition in which the molecular weight of said polyvinyl acetate composition is between about 80,000 and 150, 000.
Claim 2
Dependent Claim

A decorative laminate according to claim 1 wherein the core sheet is coated on its exposed surface with said adherable coating composition in which the cold flow test value of said polyvinyl acetate composition is between about 500 to 1,200.
Claim 4
Dependent Claim
57 words
A decorative laminate according to claim 1 wherein the core sheet is coated on its exposed surface with said adhesive coating composition in which the particle size range of said polyvinyl acetate composition is between about 0.5 and 10 microns and the cold flow test value of said polyvinyl acetate composition is between about 500 and 1,200.
Claim 5
Dependent Claim
65 words
A decorative laminate according to claim 1 wherein the core sheet is coated on its exposed surface with said adhesive coating composition in which said plasticizer is present in an amount between about 3 and 8 percent, said protective colloid is present in an amount between about 2 and 5 percent and said starch is present in an amount between about 0.5 and 2 percent.
