Abstract

An electrostatographic imaging member including: (a) a substrate; (b) a layer including a vinyl acetate composition; and (c) an imaging layer.

Claims

1. An electrostatographic imaging member comprising:

(a) a substrate;

(b) a charge blocking layer;

(c) an adhesive layer including a vinyl acetate composition; and

(d) an imaging layer.

2. The member of claim 1, wherein the adhesive layer consists of the vinyl acetate composition.

3. The member of claim 1, wherein the adhesive layer further includes an organosilane.

4. The member of claim 1, wherein the adhesive layer further includes a plurality of inorganic oxide particles coated with an organosilane.

5. The member of claim 1, wherein the vinyl acetate composition includes a poly(vinyl alcohol-vinyl acetate) copolymer.

6. The member of claim 5, wherein vinyl alcohol monomer is present in an amount ranging from about 50% to about 75% by mole percent based on the copolymer, and the vinyl acetate is present in an amount ranging from about 50% to about 25% by mole percent based on the copolymer.

7. The member of claim 1, wherein the vinyl acetate composition includes a polyvinyl acetate hompolymer.

8. The member of claim 1, wherein the vinyl acetate composition includes polyvinyl alcohol and a poly(vinyl alcohol-vinyl acetate) copolymer.

9. The member of claim 1, wherein the vinyl acetate composition includes hydroxyethyl cellulose and polyvinyl acetate homopolymer.

10. The member of claim 1, wherein the vinyl acetate composition includes dextrin and polyvinyl acetate homopolymer.

11. The member of claim 1, wherein the vinyl acetate composition includes polyvinyl alcohol and a polyvinyl acetate homopolymer.

12. The member of claim 1, wherein the imaging layer is a charge generating layer and further comprising (e) a charge transport layer.

13. An electrostatographic imaging member comprising:

(a) a substrate;

(b) a charge blocking adhesive layer including a vinyl acetate composition; and

(c) an imaging layer, wherein there is absent a charge blocking layer disposed between the substrate and the charge blocking adhesive layer, and there is absent an adhesive layer disposed between the charge blocking adhesive layer and the imaging layer.

14. The member of claim 13, wherein the charge blocking adhesive layer consists of the vinyl acetate composition.

15. The member of claim 13, wherein the charge blocking adhesive layer further includes an organosilane.

16. The member of claim 13, wherein the charge blocking adhesive layer further includes a plurality of inorganic oxide particles coated with an organosilane.

17. The member of claim 13, wherein the vinyl acetate composition includes a poly(vinyl alcohol-vinyl acetate) copolymer.

18. The member of claim 17, wherein vinyl alcohol monomer is present in an amount ranging from about 50% to about 75% by mole percent based on the copolymer, and the vinyl acetate is present in an amount ranging from about 50% to about 25% by mole percent based on the copolymer.

19. The member of claim 13, wherein the vinyl acetate composition includes a polyvinyl acetate hompolymer.

20. The member of claim 13, wherein the vinyl acetate composition includes polyvinyl alcohol and a poly(vinyl alcohol-vinyl acetate) copolymer.

21. The member of claim 13, wherein the vinyl acetate composition includes hydroxyethyl cellulose and polyvinyl acetate homopolymer.

22. The member of claim 13, wherein the vinyl acetate composition includes dextrin and polyvinyl acetate homopolymer.

23. The member of claim 13, wherein the vinyl acetate composition includes polyvinyl alcohol and a polyvinyl acetate homopolymer.

24. The member of claim 13, wherein the imaging layer is a charge generating layer and further comprising (d) a charge transport layer.

25. The member of claim 13, wherein the charge blocking adhesive layer further includes a charge blocking material.
