Abstract

There is described a coating composition useful for forming a transfer member suitable for use with an image forming system. The composition includes coating an ultraviolet (UV) curable mixture comprising a chlorinated polyester resin, a reactive diluent, conductive species and a photoinitiator on a substrate. The UV curable mixture is cured with ultraviolet energy. The cured mixture is then removed from the substrate.

Claims

1. A coating composition, comprising:

a mixture of an ultraviolet (UV) curable mixture comprising a chlorinated polyester resin, a reactive diluent, conductive species consisting of esters of phosphoric acid and esters of fatty acids and a photoinitiator wherein the conductive species comprises from about 5 to 30 weight percent of the mixture.

2. The coating composition of claim 1 wherein the conductive species further comprises a material selected from the group consisting of salts of organic sulfonic acid, ammonium salts, phosphonium salts and mixtures thereof.

3. The coating composition of claim 1, wherein the reactive diluent is selected from the group consisting of trimethylolpropane triacrylate, hexandiol diacrylate, tripropyleneglycol diacrylate, dipropyleneglycol diacrylate, proxylated neopentylglycol diacrylate, hexamethylene diacrylate and mixtures thereof.

4. The coating composition of claim 1, wherein the photoinitiator is selected from the group consisting of acyl phosphines, α

-hydroxyketones, benzyl ketals, α

-aminoketones, and mixtures thereof.

5. The coating composition of claim 1 wherein the chlorinated polyester is formed from a reaction of maleic acid at a weight percent of from about 10 to about 50, adipic acid at a weight percent of from about 5 to about 45, diethylene glycol at a weight percent of from about 5 to about 45, and a chlorinated aliphatic diol at a weight percent of from about 5 to about 40.

6. The coating composition of claim 1 wherein the chlorinated polyester comprises a number average molecular weight (Mn) of from about 500 to about 5,000.

7. The coating composition of claim 1 wherein the chlorinated polyester comprises a weight average molecular weight (Mw) of from about 1,000 to about 20,000.

8. A coating composition, comprising:

a mixture of an ultraviolet (UV) curable mixture comprising a chlorinated polyester resin, a reactive diluent selected from the group consisting of trimethylolpropane triacrylate, hexandiol diacrylate, tripropyleneglycol diacrylate, dipropyleneglycol diacrylate, proxylated neopentylglycol diacrylate, hexamethylene diacrylate and mixtures thereof, conductive species consisting of esters of phosphoric acid and esters of fatty acids and a photoinitiator wherein the conductive species comprises from about 5 weight percent to about 30 weight percent of the mixture.

9. The coating composition of claim 8 wherein the conductive species further comprises a material selected from the group consisting of salts of organic sulfonic acid, ammonium salts, phosphonium salts and mixtures thereof.

10. The coating composition of claim 8, wherein the photoinitiator is selected from the group consisting of acyl phosphines, α

-hydroxyketones, benzyl ketals, α

-aminoketones, and mixtures thereof.

11. The coating composition of claim 8 wherein the chlorinated polyester is formed from a reaction of maleic acid at a weight percent of from about 10 to about 50, adipic acid at a weight percent of from about 5 to about 45, diethylene glycol at a weight percent of from about 5 to about 45, and a chlorinated aliphatic diol at a weight percent of from about 5 to about 40.

12. The coating composition of claim 8 wherein the chlorinated polyester comprises a number average molecular weight (Mn) of from about 500 to about 5,000.

13. The coating composition of claim 8 wherein the chlorinated polyester comprises a weight average molecular weight (Mw) of from about 1,000 to about 20,000.
