Abstract

Disclosed are curable polymer compositions, elastomers thereof and release layers useful in the art of printing made of the disclosed elastomers. Disclosed are also intermediate transfer members having a release layer useful in the art of printing. Disclosed are anisotropic intermediate transfer members. Disclosed are curable adhesive compositions, that in some embodiments are useful in preparing intermediate transfer members useful in printing. Also disclosed are intermediate transfer members useful in the art of printing having a release layer with an image transfer surface having protonatable functional groups apparent thereupon. Also disclosed are methods of making such intermediate transfer members.

First claim

1 . An intermediate transfer member for use with a printing system, comprising:
a longitudinal direction and a lateral direction; a release layer having an image transfer surface; and said release layer attached to a body supporting said release layer, wherein said body is configured so that the intermediate transfer member has a substantially greater elasticity in said lateral direction than in said longitudinal direction.

2 . The intermediate transfer member of claim 1 , being substantially inelastic in said longitudinal direction.

3 . The intermediate transfer member of claim 1 , wherein said intermediate transfer member, when maintained at a temperature of about 150° C., is configured to stretch in said longitudinal direction by not more than about 1.5% under normal operating conditions.

4 . The intermediate transfer member of claim 1 , being substantially elastic in said lateral direction.

5 . The intermediate transfer member of claim 1 , wherein said intermediate transfer member, when maintained at a temperature of about 150° C., is configured to elastically stretch in said lateral direction by not less than about 5%.

6 . The intermediate transfer member of claim 1 , said body including a plurality of primary fibers oriented substantially parallel to said longitudinal direction.

7 . The intermediate transfer member of claim 6 , wherein said primary fibers are substantially inelastic.

8 . The intermediate transfer member of claim 6 , wherein said primary fibers comprise a material selected from the group consisting of organic polymer fibers, meta-aramid, para-aramid, polyamide, nylon fibers, polyester fibers, natural fibers, cotton fibers, inorganic fibers, glass fibers, carbon-fiber fibers, ceramic fibers, metal fibers and combinations thereof.

9 . The intermediate transfer member of claim 6 , wherein said primary fibers consist of glass fibers.

10 . The intermediate transfer member of claim 6 , said body further comprising at least one supporting component.

11 . The intermediate transfer member of claim 10 , wherein a said supporting component comprises a non-fibrous elastomer.

12 . The intermediate transfer member of claim 11 , said elastomer comprising a material selected from the group consisting of silicone rubber, neoprene rubber, hydrogenated nitrile butadiene rubber (HNBR), nitrile butadiene rubber (NBR), alkyl acrylate copolymer (ACM), ethylene propylene diene monomer (EPDM) and combinations thereof.

13 . The intermediate transfer member of claim 11 , wherein said primary fibers are impregnated with said elastomer.

14 . The intermediate transfer member of claim 11 , wherein said primary fibers are embedded within said elastomer.

15 . The intermediate transfer member of claim 11 , wherein a said supporting component is substantially a distinct sheet of said elastomer.

16 . The intermediate transfer member of claim 15 , wherein said primary fibers are in direct physical contact with said sheet of said elastomer.

17 . The intermediate transfer member of claim 10 , wherein a said supporting component comprises secondary fibers, distinct from said primary fibers.

18 . The intermediate transfer member of claim 17 , wherein said secondary fibers are oriented substantially not-parallel to said primary fibers.

19 . The intermediate transfer member of claim 18 , wherein said secondary fibers are oriented to diverge by at least about 30° from parallel to said primary fibers.

20 . The intermediate transfer member of claim 18 , wherein said secondary fibers are oriented substantially parallel to said lateral direction.

21 - 69 . (canceled)
