Abstract:
An article, having applied to a portion thereof, an adhesive composition, wherein the adhesive composition comprises:(a) an adhesive carrier; and(b) an adhesively effective amount of a polyamino acid salt selected from the group consisting of polyaspartic acid salts represented by Formula (1): ##STR17##polyglutamic acid salts represented by Formula (2); ##STR18##and copolymers of the polyaspartic acid salts represented by Formula (1) with the polyglutamic acid salts represented by Formula (2), and mixtures thereof; wherein(i) M.sup.+ is selected from the group consisting of a mixture of Ca.sup.2+ and Na.sup.+ cations present in a ratio from about 25:75 to about 95:5, respectively; a mixture of Zn.sup.2+ and Na.sup.+ cations present in a ratio from about 25:75 to about 80:20, respectively; a mixture of Ca.sup.2+ and NH.sub.4.sup.+ cations present in a ratio from about 25:75 to about 95:5, respectively; a mixture of Zn.sup.2+ and NH.sub.4.sup.+ cations present in a ratio from about 25:75 to about 80:20, respectively; monovalent and multivalent organic quaternary ammonium cations; and monofunctional and multifunctional amines;(ii) the ratio of n.sub.1 to n.sub.2 is from about 1:99 to about 99:1; and(iii) the molecular weight of the polyamino acid salt is from about 1,000 to about 1,000,000.
