The present invention provides an aqueous polyurethane dispersion (PUD) comprising an amorphous polyester having a glass transition temperature (Tg) as determined by differential scanning calorimetry of less than −30° C.; wherein the aqueous polyurethane dispersion (PUD) has a glass transition temperature (Tg) as determined by differential scanning calorimetry (DSC) of 0° C. to 20° C. and a hard block content of greater than 50% and wherein the aqueous polyurethane dispersion (PUD) provides resistance to one or more selected from the group consisting of 10% HCl, water, motor oil, diesel fuel, 10% acetic acid, methyl ethyl ketone and 25% NaOH. Coatings, adhesives, sealants, paints, primers, and topcoats, made from the inventive aqueous polyurethane dispersion (PUD) provide good chemical resistance to a variety of surfaces including floors, windows, doors, window frames, door frames, window shutters, railing, gates, pillars, arbors, pergolas, trellises, gazebos, posts, fencing, pipes and fittings, wire and cable insulation, automobile components, credit cards, and siding.
