Abstract
The present invention is related to the production of coatings utilizing a fluorine-containing polymer having hydroxyl and/or carboxyl groups that are cured with an amino resin to produce 'soft hand' low gloss coatings for vinyl, urethane, leather, and other flexible plastic substrates. A method for increasing the stain resistance of a flexible substrate comprises providing a fluorine-containing ethylene-based copolymer containing fluorine atoms in the main chain of the polymer and pendent reactive groups selected from the group consisting of carboxyl groups, hydroxyl groups and combinations thereof; providing an amino resin; mixing the copolymer and the amino resin; applying the mixed copolymer and amino resin to a flexible substrate; and curing the mixed copolymer and amino resin to provide a coated substrate having a soft hand wherein the stain resistance of said coated substrate is improved over that of the uncoated substrate.
