| 发明名称 | Linear polyester resins and improved lithographic inks | ||
| 摘要 | The present invention describes a linear polyester resin comprising a di-epoxide monomer and a di-acid monomer useful in energy curable lithographic inks. The linear polyester resin exhibits a number average molecular weight less than 20,000. The present invention also describes an energy curable lithographic ink formulation including the linear polyester resin. The ink exhibits improved print density, print contrast, water window and rheological (total body) characteristics. | ||
