Abstract

A member composed of a base layer having a seam and a top layer having a seam, an adhesive layer between the base layer and the top layer, wherein the base layer seam is discontinuously offset from the top layer seam.

Claims

1. A member comprising:

a base layer having a seam and a top layer having a seam, an adhesive layer between the base layer and the top layer, wherein the base layer seam is discontinuously offset from the top layer seam.

2. The member of claim 1, wherein the adhesive layer is seamed, wherein the adhesive layer seam is discontinuously offset from the top layer seam and the bottom layer seam.

3. The member of claim 1, wherein the base layer is comprised of polycarbonate.

4. The member of claim 1, wherein the top layer is comprised of polyvinyl fluoride.

5. The member of claim 1, wherein the member has two parallel edges and the base layer seam has an oblique angle with respect to the two edges.

6. The member of claim 1, wherein the member has two parallel edges and the top layer seam has an oblique angle with respect to the two edges.

7. The member of claim 1, wherein the difference in thickness between the top layer seam and the unseamed portion of the top layer is less than about 100 microns and the difference in thickness between the base layer seam and the unseamed portion of the base layer is less than about 100 microns.

8. The member of claim 1, wherein the member is an endless belt.

9. The member of claim 1, further comprising electrical property regulating particles disposed in only the base layer.

10. The member of claim 1, further comprising electrical property regulating particles disposed in both the base layer and the top layer.

11. The member of claim 1, wherein the member has a charge relaxation time of less than about 2×

10² seconds.

12. The member of claim 1, further comprising electrical property regulating particles disposed in the base layer, the adhesive layer, and the top layer.

13. The member of claim 1, wherein the top layer has a surface energy ranging from about 17 to about 37 dyn/cm.

14. A member comprising:

(a) a base layer having a seam;

(b) a first adhesive layer;

(c) an intermediate layer having a seam;

(d) a second adhesive layer; and

(e) a top layer having a seam, wherein the intermediate layer seam is discontinuously offset from both the base layer seam and the top layer seam.

15. The member of claim 14, wherein the first adhesive layer is seed and the second adhesive layer is seamed, wherein the first adhesive layer seam and the second adhesive layer seam are discontinuously offset from one another and from the base layer seam, the intermediate layer seam, and the top layer seam.
