Application No. 08/432,560
This is an appeal under 35 U.S.C. § 134 from the
examiner’s refusal to allow claims 5 through 13 which are all
of the claims remaining in the application.
THE INVENTION
Appellants’ invention is directed to a water containing
coating composition having a specific emulsifier which is an
ammonium salt of a mono sulfuric acid ester of adducts
prepared by ethoxylation of long chain alcohols or substituted
phenols. There are two components present in the composition
in addition to the emulsifier. The first component is a
polyol which is a polymer of an emulsion polymerized
ethylenically unsaturated monomer having at least two hydroxy
groups per molecule and being dispersed in water. Said
hydroxy containing polymer is emulsion polymerized in the
presence of the above named emulsifier.
The second component is an aliphatic or cycloaliphatic
polyisocyanate emulsified in the dispersion of the hydroxy
containing polymer.
