Claim Text:
1. An article comprising: a flexible material of a non-woven, the flexible material treated with a binder composition of (a) one or more polycarboxy emulsion copolymer polymerized from 10 wt. % to 25 wt. % of a carboxy acid monomer, based on the total weight of monomers in the copolymer, wherein the polycarboxy emulsion copolymer has a measured Tg of from −45° C. to 25° C., and a total solids of no less than 40 wt. %; and, (b) at least one polyol crosslinker having a molecular weight of less than 700, the polyol crosslinker comprising a primary hydroxy group and at least one additional hydroxy group, wherein the ratio of primary hydroxy group equivalents to carboxy group equivalents is from 0.25:1 to 2.0:1, wherein, the flexible material is selected from (i) a facing sheet chosen from a fibrous sheet, roving, mat or a pultruded fibrous material in a gypsum wallboard or panel comprising a gypsum core layer sandwiched between facing sheets and (ii) a sheet, roving or mat which is a carpet backing.
