The use of dimer acids with conventional hot melt adhesive polymers provide adhesives particularly useful for bottle labeling. The label, along with the adhesive, can be easily removed from the bottle during the recycling process.

Labeling adhesive

A wetness indicating hot melt adhesive composition comprising a pH adjusting component and an indicating agent which is capable of changing color in response to changes in pH. The adhesive composition may comprise 20 to 80% by weight of a sulfonated polyester, 3 to 30% by weight of an acidic plasticizer and 0.05 to 3% by weight of an indicator.

Hot melt adhesives based on sulfonated polyesters comprising wetness indicator

A hot melt adhesive composition comprising (a) greater than 40% by weight of a polymeric component; and (b) 5 to 40% by weight of a high hydroxyl number compound, with hydroxyl number greater than 100 mg KOH/g.

Use of high hydroxyl compounds for water sensitive hot melt adhesives

This invention relates to an adhesive composition which 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, polyglutamic acid salts, and copolymers of polyaspartic acid salts with polyglutamic acid salts, and mixtures thereof. The present invention also pertains to an article to which the adhesive composition has been applied, a method for adhering a first substrate to a second substrate employing the polyamino acid salts, and to an improved method for making polyamino acid salts.

Use of polyamino acid salts in water-borne adhesive applications

A remoistenable hot melt adhesive composition comprising (i) 25 to 80% by weight of a sulfonated polyester;

Use of anionic or cationic plasticizers with sulfonated polyesters in

A hot melt adhesive composition comprising
