摘要： An aqueous dispersion containing a polyamide and non-polyamide polymer is prepared by dissolving the polyamide in an organic solvent with a surfactant to form a polyamide solution. Water is then added to the polyamide solution to form an aqueous dispersion. The non-polyamide polymer can be added before or after the addition of water. The polyamide/non-polyamide dispersion can be used to produce an ink with better adhesion to plastic substrates and reduced blocking problems.

摘要： A method for formulating an aqueous dispersion of a polymer includes dissolving a polymer such as an acrylic polyol in a solvent to form a polymer solution. A surfactant is added to the polymer solution, and water is then added with mixing sufficient to dispersed the polymer in the water. The resulting aqueous dispersion can be mixed with a water dispersible polyisocyanate to produce coating materials which can be cured to form tough films and coatings.

摘要： A polymer useful as an inorganic pigment dispersant is provided. The polymer is derived from monomers consisting essentially of an ethylenically unsaturated aromatic monomer, an ethylenically unsaturated dicarboxylic acid monomer, and an ethylenically unsaturated monocarboxylic acid monomer. The total amount of said ethylenically unsaturated acid monomers is sufficient to permit said polymer to associate with an inorganic pigment in an aqueous medium in a manner which disperses said inorganic pigment in said aqueous medium to form a stable aqueous dispersion of said inorganic pigment, and the amount of said ethylenically unsaturated aromatic monomer is sufficient to reduce the water sensitivity of a dried coating of a latex paint comprised of said stable aqueous dispersion of said inorganic pigment. A process of preparing a polymer useful as an inorganic pigment dispersant and a method of preparing an inorganic pigment dispersion useful in the preparation of latex paints are also provided.
