Claims21
An adhesive composition comprising:
- (a) a water soluble or water dispersible polymer having adhesive properties present in an amount of about 5 to 50% by weight of the total weight of the adhesive composition;
- (b) an N-fatty acid acylated amino acid or a salt thereof present in an amount of about 2 to about 30% by weight of the total amount of the adhesive composition;
- and
- (c) water or a mixture of water and one or more organic solvent(s) and/or one or more plasticizer(s), wherein the proportion of said water or said mixture of water and one or more organic solvent(s) and/or one or more plasticizer(s) contained in the adhesive composition is about 30 to 80% by weight of the total adhesive composition, but the proportion of the one or more organic solvent(s) and/or one or more plasticizer(s) is less than the amount of water together therewith.
