Abstract:
A laundry article effective for inhibiting transfer of extraneous dyes and soil to articles in a wash liquor, said laundry article comprising(I) a support matrix; and(II) a functionalized polyamine attached to or entrapped in the support matrix, wherein the support matrix contains from about 0.01 to about 50 weight percent of the functionalized polyamine, based on the weight of functionalized polyamine and support matrix, and the functionalized polyamine comprises the reaction product of (A) a cyano- or guanidino-containing compound selected from the group consisting of cyanamides or salts thereof, dicyanamides or salts thereof, dicyandiamides or salts thereof, guanidines or salts thereof, biguanidines or salts thereof, and combinations thereof, and (B) a polyamine prepared from at least one monomeric amine, wherein the cyano- or guanidino-functional groups are attached to the polyamine or incorporated therein to form the functionalized polyamine, provided that the monomeric amine and the cyano- or guanidino-containing compound are present in the functionalized polyamine in a molar ratio of from about 0.1:1 to about 10:1, respectively, wherein the functionalized polyamine has the structureH.sub.2 N--R.sub.1 --[--N(R.sub.2).sub.q R.sub.3 --].sub.w --[--NH.sub.2 ].sub.xwherein R.sub.1 is selected from the group consisting of C.sub.1 -C.sub.20 alkyl, aryl, alkaryl, and --(CH.sub.2 CHXO).sub.p --;
