Abstract:
A non-blocking film or fiber comprising a water-dispersible polymer composition comprising:(I) the sulfopolyester comprised of(i) monomer residues of at least one dicarboxylic acid; and(ii) up to about 75 monomer residues of at least one diol wherein said diol is other than a poly(alkylene glycol); and(iii) about 4 to 25 mole percent, based on the total of all acid and hydroxy equivalents, of monomer residues of at least one difunctional sulfomonomer containing at least one sulfonate group bonded to an aromatic ring, wherein the functional groups are hydroxy or carboxyl; and optionally(iv) monomer residues of at least one poly(alkylene glycol) having the formula --(OCH.sub.2 CH.sub.2).sub.n -- wherein n is 20 about 500, provided that the mole percent of such residues is inversely proportional to the value of n;(II) about 10 to 75 weight percent of a pigment or filler; and (III) a wax.
