Abstract:
A coating composition includes: (a) a first acrylic polymer formed from a reaction mixture including: (i) an ethylenically unsaturated monomer including an acid group or an amine group; (ii) a reactive solvent reactive with the ethylenically unsaturated monomer (i); and (iii) a second monomer reactive with ethylenically unsaturated monomer (i); and (b) a second acrylic polymer different from the first acrylic polymer, where the second acrylic polymer (b) has a Mw of at least 100,000 Da. A method of preparing such a coating composition and coatings and coated substrates formed therefrom are also disclosed. Coatings formed from the disclosed coating composition may exhibit improved stain resistance.
