Claims
- 1. An adhesive composition comprising water, 20 to 80% by weight of a water soluble adhesive polymer, an amount of at least one styrene maleic anhydride copolymer sufficient to provide 4.8 to 20 parts styrene maleic anhydride per 100 parts adhesive polymer, 0.5 to 25% by weight of a rosin, and sufficient base to give a pH within the range of 7 to 11, wherein when said rosin is an acid rosin, said acid rosin has an acid number of less than 140.
- 2. The adhesive of claim 1 wherein the styrene maleic anhydride copolymer has a styrene to maleic anhydride ratio of 1:1 to 3:1.
- 3. The adhesive of claim 1 wherein the adhesive polymer is a natural polymer.
- 4. The adhesive of claim 3 wherein the adhesive polymer comprises starch.
- 5. The adhesive of claim 3 wherein the adhesive polymer is a synthetic polymer.
- 6. The adhesive of claim 5 wherein the adhesive polymer comprises a polymer selected from the group consisting of polyvinyl pyrrolidone, polyacrylic acid, polyvinyl alcohol, ethylene vinyl acetate polymers and, vinyl acetate polymers and copolymers, polyvinyl acrylate homopolymers, acrylic polymers, styrene butadiene polymers, polyurethanes, neoprene and styrene acrylic polymers.
- 7. The adhesive of claim 1 wherein the base comprises ammonium hydroxide.
- 8. The adhesive of claim 7 wherein the base further comprises sodium hydroxide.
- 9. The adhesive of claim 1 wherein the base comprises a volatilized nitrogen base.
- 10. The adhesive of claim 1 further comprising a peptizer.
- 11. A labeled bottle comprising the adhesive of claim 1.
- 12. The bottle of claim 11 wherein the label is formed of a material selected from the group consisting of paper, polymer films, foil, metallized films, film to polyester sheets, woven fabrics and nonwoven fabrics.
- 13. The bottle of claim 12 wherein the label is formed of paper, a polymer film or a metallized polymer.
- 14. A method of applying a label to a container comprising applying the adhesive of claim 1 to a label, applying the label to a container, and drying the adhesive.
- 15. The method of claim 14 wherein the container is a bottle.
- 16. The method of claim 15 wherein the label is formed of paper, a polymer film or a metallized polymer.
- 17. A process of removing a label from the labeled bottle of claim 11 comprising submerging the labeled bottle in a caustic solution for a time sufficient to remove the label from the labeled bottle.
- 18. The process of claim 17 wherein the caustic solution comprises a 3% potassium hydroxide solution.
