2. The tissue paper of claim 1 wherein said tissue paper has a density of less than about 0.15 gram/cm.sup.3.

3. The tissue paper of claim 1 wherein said tissue paper is a single-ply tissue.

4. The tissue paper of claim 1 wherein said tissue paper is a multi-layer tissue.

5. The tissue paper of claim 1 wherein said tissue paper is made by a through air drying technique.

6. The tissue paper of claim 1 wherein said ATP factor of less than about 0.030.

7. The tissue paper of claim 6 wherein said slip/stick coefficient is less than about 0.022.

8. The tissue paper of claim 7 wherein said tissue paper has a density of less than about 0.10 gram/cm.sup.3.

9. The tissue paper of claim 8 wherein said tissue paper is a single-ply tissue.

10. The tissue paper of claim 8 wherein said tissue paper is a multi-layer tissue.

11. The tissue paper of claim 8 wherein said tissue paper is made by a through air drying technique.

12. The tissue paper of claim 8 wherein said tissue paper comprises a mixture of softwood and hardwood fibers.

13. The tissue paper of claim 12 wherein said binder materials are permanent wet strength binders selected from the group consisting of polyamide-epichlorohydrin resins, polyacrylamide resins, and mixtures thereof.

14. The tissue paper of claim 12 wherein said binder materials are temporary wet strength binders selected from the group consisting of cationic dialdehyde starch-based resins, dialdehyde starch resins and mixtures thereof.

15. The tissue paper of claim 12 wherein said binder materials are dry strength binders selected from the group consisting of carboxymethyl cellulose resins, starch based resins, and mixtures thereof.

16. The tissue paper of claim 1 wherein said tissue paper is made by a mechanical dewatering technique.

17. The tissue paper of claim 16 wherein said tissue paper is a single-ply tissue.

18. The tissue paper of claim 16 wherein said tissue paper is a multi-ply tissue.

19. The tissue paper of claim 16 wherein said tissue paper is a multi-layer tissue paper.

20. The tissue paper of claim 16 wherein said tissue paper has a density of less than about 0.15 gram/cm.sup.3.

21. The tissue paper of claim 1 wherein said tissue paper is toilet tissue paper.
