Patent ID: 7544413

Claim:
A film-forming composition, comprising: a film-forming binder comprising at least one of an acrylic polymer, a modified acrylic polymer, a polyurethane polymer, a polyester prepared by the polyesterification of organic polycarboxylic acids or their anhydrides with organic polyols comprising primary or secondary hydroxyl groups, a polyester polyurethane polymer, or a combination thereof; and a pigment mixture, said pigment mixture present in a pigment to binder ratio of 0.8 to 0.99, and consisting of: (i) at least 80% of titanium dioxide by weight, based on the total weight of the pigment mixture; and (ii) no more than 20% by weight of non-titanium dioxide pigments based on the total weight of the pigment mixture, said non-titanium dioxide pigments being selected from the group consisting of carbon black, talc, barium sulfate, magnesium silicate, and combinations comprising two or more of the foregoing; wherein the film-forming composition has an adjusted VOC of no more than 100 g/L, is free of all pigments other than those in the pigment mixture, has a viscosity of no more than 200 cps at 384 sec −1 , and when cured for 25 minutes at 150C. provides a cured film having an elasticity of at least 20% at a dry film build of from 0.8 to 2.0 mil on cold rolled steel.
