Abstract

Claims (17)

1. A composition for forming a flexible transfer film comprising a polymerizable resin monomer or a resin and an internal bifunctional polymerizable release agent, wherein said polymerizable release agent is present in an amount of no more than about 8% by weight, wherein said polymerizable release agent is selected from the group consisting of 2,2,2-trifluoro methacrylate, trifluoroethyl methacrylate, 1,1,1,3,3,3-hexafluoro isopropyl methacrylate, 2,2,2-trifluoro-1-(trifluoromethyl) ethyl methacrylate, 1,1,1,3,3,3-hexafluoro isopropyl acrylate, trifluoromethyl methacrylate, 3-methacryloxypropyltrimethoxysilane, 3-methacryloxypropylethoxysilane, methacryloxymethyltriethoxysilane and acryloxypropyltrimethoxysilane, and said release agent polymerizes on exposure to an elevated temperature.

2. The composition of claim 1 , further comprising an electrical property regulating material.

3. The composition of claim 2 , wherein said material comprises a carbon black.

4. The composition of claim 1 , wherein said polymerizable resin monomer polymerizes on exposure to an elevated temperature.

5. A flexible transfer film comprising a resin and an internal bifunctional polymeric release agent selected from the group consisting of 2,2,2-trifluoro methacrylate, trifluoroethyl methacrylate, 1,1,1,3,3,3-hexafluoro isopropyl methacrylate, 2,2,2-trifluoro-1-(trifluoromethyl) ethyl methacrylate, 1,1,1,3,3,3-hexafluoro isopropyl acrylate, trifluoromethyl methacrylate, 3-methacryloxypropyltrimethoxysilane, 3-methacryloxypropylethoxysilane, methacryloxymethyltriethoxysilane and acryloxypropyltrimethoxysilane, wherein said polymerizable release agent is present in an amount of no more than about 8% by weight.

6. The member of claim 5 , further comprising an electrical property regulating material.

7. The member of claim 6 , wherein said material comprises a carbon black.

8. An imaging device comprising the transfer film of claim 5 .

9. A method of preparing a flexible transfer film without using an external release agent comprising:

a) applying to a form, mold or mandrel a film-forming composition comprising a resin-forming monomer or a resin and a bifunctional polymerizable release agent selected from the group consisting of 2,2,2-trifluoro methacrylate, trifluoroethyl methacrylate, 1,1,1,3,3,3-hexafluoro isopropyl methacrylate, 2,2,2-trifluoro-1-(trifluoromethyl) ethyl methacrylate, 1,1,1,3,3,3-hexafluoro isopropyl acrylate, trifluoromethyl methacrylate, 3-methacryloxypropyltrimethoxysilane, 3-methacryloxypropylethoxysilane, methacryloxymethyltriethoxysilane and acryloxypropyltrimethoxysilane, which polymerizes on exposure to an elevated temperature, to yield a coated form, mold or mandrel, wherein said polymerizable release agent is present in an amount of no more than about 8% by weight;

b) exposing the coated form, mold or mandrel of step a) to an elevated temperature to yield a polymerized flexible transfer film; and

c) removing said flexible transfer film from said form, mold or mandrel.

10. The method of claim 9 , wherein said composition comprises an electrical property regulating material.

11. The method of claim 10 , wherein said material comprises a carbon black.

12. The composition of claim 1 , wherein the bifunctional release agent is trifluoroethyl methacrylate.

13. The film of claim 5 , wherein the bifunctional polymeric release agent is trifluoroethyl methacrylate.

14. The method of claim 9 , wherein the bifunctional polymeric release agent is trifluoroethyl methacrylate.
