Imperial Chemical Industries has obtained a patent for a pigmented, aqueous coating comprised of an aqueous dispersion of non-crosslinkable addition oligomer of weight average molecular weight of 5000 to 15000 Daltons and calculated Fox Tg greater than 0[degrees] C and less than 50[degrees] C, an aqueous dispersion of addition polymer of weight average molecular weight greater than 53,000 Daltons, calculated Fox Tg greater than 10[degrees] C and less than 40[degrees] C and mean particle diameter of less than 150 nanometers and the ratio is from 0.25:1 to 2.70:1 based on % weight dispersion solids and a pigment, and wherein the composition has an open time of 6[+ or -]1 to 12[+ or -]3 minutes, and never more than 15 minutes; and when dry has a gloss of at least 75%.
has obtained a patent for a method comprised of providing an oxirane-functional vinyl addition polymer having an oxirane functionality of 0.5 to 5; providing an acid-functional polymer having an acid number of 30 to 500; reacting the oxirane-functional vinyl addition polymer and the acid-functional polymer together in the presence of a tertiary amine to form a water-dispersible polymer; and dispersing the water-dispersible polymer in a carrier comprised of water.
