Abstract

An aqueous adhesive composition with good release properties. A preferred embodiment comprises sodium lauryl sulfate and a modified tapioca dextrin.

Claims (17)

1. A composition comprising a surfactant and an amount of a polysaccharide effective to provide fugitive adhesive properties.

2. The composition of claim 1 wherein the polysaccharide is a starch.

3. The composition of claim 2 wherein the starch is a modified dextrin.

4. The composition of claim 3 wherein the modified dextrin is a modified tapioca dextrin.

5. The composition of claim 4 wherein the surfactant is sodium lauryl sulfate.

6. An article of manufacture comprising the composition of claim 1 .

7. The article of claim 6 wherein the polysaccharide in said composition comprises a starch.

8. The article of claim 7 wherein the starch is a modified tapioca dextrin.

9. The article of claim 8 wherein the surfactant in said composition comprises sodium lauryl sulfate.

10. The article of claim 6 which is a rolled paper product.

11. The article of claim 10 which is a coreless rolled paper product.

12. The article of claim 10 wherein the polysaccharide in said composition comprises a modified tapioca dextrin and the surfactant in said composition comprises sodium lauryl sulfate.

13. A process for temporarily bonding a first substrate to a similar or dissimilar second substrate comprising applying the composition of claim 1 to at least a first substrate, bringing a second substrate in contact with the composition applied to the first substrate, whereby the first and second substrates are fugitively bonded together.

14. The process of claim 13 wherein the composition comprises a starch.

15. The process of claim 14 wherein the starch is a modified tapioca dextrin.

16. A coreless rolled paper product wherein an effective amount of the composition of claim 1 is applied to a first portion of the paper and the paper is then would to form a self supporting roll.

17. The coreless paper product of claim 16 wherein the composition comprises a modified tapioca dextrin and sodium lauryl sulfate.
