Abstract

Water-based compositions containing a low VOC coalescent, a latex or water-dispersible polymer, and a water-insoluble UV-VIS (preferably, ultraviolet) absorber.

First claim

1 - 22 . (canceled)

23 . A latex-based paint comprising:
a latex polymer; and methyl-o-benzoyl benzoate; wherein the paint includes no greater than 50 grams of total VOC per 100 grams polymer solids; and wherein the paint has a pigment volume concentration range of 20 to 75.

24 . The composition of claim 23 wherein the composition includes no greater than 25 grams of total VOC per 100 grams polymer solids.

25 . The composition of claim 24 wherein the composition includes no greater than 20 grams of total VOC per 100 grams polymer solids.

26 . The composition of claim 25 wherein the composition includes no greater than 10 grams of total VOC per 100 grams polymer solids.

27 . The paint of claim 26 wherein the latex polymer is not a multi-stage latex polymer.

28 . The paint of claim 26 wherein the latex polymer comprises the polymerization product of ethylenically unsaturated monomers comprising acetoacetyl ethyl methacrylate (AAEM), diacetone acrylamide, or mixtures thereof.

29 . The paint of claim 26 wherein the latex polymer comprises the polymerization product of ethylenically unsaturated monomers that do not include styrene.

30 . The paint of claim 26 wherein the latex polymer comprises a surfactant and polymer particles comprising a copolymer including at least one of an acrylate or a methacrylate.

31 . The paint of claim 26 comprising at least 0.1 wt-% and up to 5.0 wt-% of methyl-o-benzoyl benzoate, based on the weight of the polymer solids.

32 . The paint of claim 23 comprising at least 0.1 wt-% and up to 5.0 wt-% of methyl-o-benzoyl benzoate, based on the weight of the polymer solids.

33 . The paint of claim 23 further comprising a defoamer and at least one of a mildewcide or a biocide.

34 . The paint of claim 23 further comprising a pigment, a defoamer, a thickener, a surfactant, a dispersant, a filler, and combinations thereof.

35 . The paint of claim 23 further comprising a surfactant.

36 . The paint of claim 35 wherein the surfactant comprises sodium laureth sulfate.

37 . The paint of claim 23 comprising sufficient TiO 2 pigment to be substantially visually opaque when applied at a thickness of 3 mils (0.0762 mm) and dried.

38 . The paint of claim 37 which has a minimum film forming temperature of less than 25° C.

39 . The paint of claim 23 which does not include a water-dispersible polymer selected from the group of a polyurethane, an epoxy, a polyamide, a chlorinated polyolefin, a polyester, and a mixture or copolymer thereof.

40 . A latex-based paint comprising:
a latex polymer comprising a copolymer including at least one of an acrylate or a methacrylate; 0.1 wt-% to 5.0 wt-% of methyl-o-benzoyl benzoate, based on the weight of the polymer solids; and one or more of a pigment, a defoamer, a thickener, a surfactant, a dispersant, and a filler; wherein the paint includes no greater than 50 grams of total VOC per 100 grams polymer solids; and wherein the paint has a pigment volume concentration range of 20 to 75.

41 . The paint of claim 40 wherein the latex polymer comprises the polymerization product of ethylenically unsaturated monomers comprising acetoacetyl ethyl methacrylate (AAEM), diacetone acrylamide, or mixtures thereof.

42 . The paint of claim 40 which has a minimum film forming temperature of less than 25° C.
