1. A curable, formaldehyde free coating composition comprising: (i) a composition comprising (a) a polyacid copolymer comprising at least two carboxylic acid groups, anhydride groups, or salts thereof, (b) a hydroxyl group-containing compound bearing at least two hydroxyl groups as an independent co
1. A curable, formaldehyde free coating composition comprising: (i) a composition comprising (a) a polyacid copolymer comprising at least two carboxylic acid groups, anhydride groups, or salts thereof, (b) a hydroxyl group-containing compound bearing at least two hydroxyl groups as an independent compound or incorporated into the polyacid copolymer backbone, and (c) a phosphorus-containing catalyst; and(ii) calcium aluminosilicate powder having a total alkali content of less than about 2 wt. % based on the total weight of the calcium aluminosilicate powder, a median particle size of about 250 microns or less, and a surface area from about 1 m2/g to about 3 m2/g,wherein the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of said hydroxyl groups is from about 1/0.01 to about 1/3. 2. The coating composition of claim 1, comprising about 20 wt. % to about 50 wt. % binder composition and about 40% wt. % to about 70 wt. % calcium aluminosilicate powder, based on the total weight of the dry components of the coating composition. 3. The coating composition of claim 1, wherein the hydroxyl group-containing compound is triethanolamine, and/or wherein the polyacid copolymer is a carboxylated acrylic copolymer. 4. The coating composition of claim 1, wherein the calcium aluminosilicate powder has a median particle size of about 20 microns or less. 5. The coating composition of claim 1, further comprising one or more components selected from the group consisting of dispersants, organic fillers, mineral fillers, pigments, surfactants, pH modifiers, buffer agents, viscosity modifiers, stabilizers, defoamers, flow modifiers, and combinations thereof. 6. The coating composition of claim 1, further comprising a filler selected from the group consisting of brighteners, clay, mica, sand, barium sulfate, silica, talc, gypsum, wollastonite, zinc oxide, zinc sulfate, hollow beads, and mixtures thereof; and/or one or more of a nonionic surfactant, and a kaolin clay. 7. The coating composition of claim 1, wherein the composition avoids formaldehyde emissions. 8. The coating composition of claim 1, wherein the calcium aluminosilicate powder has a median particle size of about 100 microns or less.
