Abstract
A composition includes at least one radiation curable (alkyl)acrylate-polyester oligomer, at least one photoinitiator, and at least one surfactant, wherein the composition has a viscosity of from about 50 cP to about 3000 cP at about 25° C., and a surface tension of from about 15 to about 40 dynes/cm at about 25° C.
Claims22
A xerographic print, comprising:
- a substrate with a toner-based image thereon, and
- an overprint composition coated over at least the toner-based image,
- wherein the overprint composition before curing has a viscosity of from about 50 cP to about 3000 cP at about 25° C. and a surface tension of from about 15 to about 40 dynes/cm at about 25° C. and comprises:
- at least one radiation curable (alkyl)acrylate-polyester oligomer,
- at least one photoinitiator, and
- at least one surfactant,
- wherein, after curing, the xerographic print resists document offset up to about 100° C.

A method of making a xerographic print, comprising:
- providing a substrate with a toner-based image thereon, and
- coating at least the toner-based image with an overprint composition, wherein the overprint composition before curing has a viscosity of from about 50 cP to about 3000 cP at about 25° C. and a surface tension of from about 15 to about 40 dynes/cm at about 25° C. and comprises:
- at least one radiation curable (alkyl)acrylate-polyester oligomer,
- at least one photoinitiator, and
- at least one surfactant, and
- exposing the coated image to a radiation source for sufficient time to substantially cure the radiation curable components of the composition.
