A method for reducing the amount of microfoam in a spray-applied clear waterborne composition is provided, the clear waterborne composition including an emulsion-polymerized addition polymer bearing at least one first reactive group and a reactive modifier bearing one second reactive group and a water-soluble group, the second reactive group being reactive with the first reactive group; applying the composition to a substrate using a spray method; and drying the composition. A reduced amount of microfoam improves the clarity of a film of the composition. Also provided are monofunctional carbodiimide reactive modifiers and substrates bearing the spray-applied clear compositions.

This invention relates to an aqueous correcting fluid, the use of which prevents bleeding of aqueous ink dyes during correction of writing errors or erasure of documents using white out. This is accomplished according to the present invention by the fact that the correcting fluid contains an anionic or non-ionic active binder plus an aminosilanes. The aminosilane-modified correcting fluid of this invention may be substituted for solvent-based fluids, without adversely affecting other properties such as water resistance, opacity and curing.

A waterborne coating composition containing an aqueous dispersion of a polymer, the polymer being substantially free from hydroxyl, primary amino, and secondary amino groups and the polymer bearing at least two active methylene groups, and an aqueous dispersion of a polyisocyanate bearing at least two isocyanate groups is provided. Also provided is a method of improving the chemical resistance of a coating and a substrate coated with the waterborne coating composition.

A method for treating substrates with an aqueous composition is provided. The aqueous composition contains an aqueous dispersion of copolymer particles which have at least two mutually incompatible phases and where the particles have an average particle size of from about 20 to about 70 nanometers.
