Preparation and characterization of UV curable-encapsulated phthalocyanine blue pigment

- Nanoscale phthalocyanine pigment was prepared through ball milling and ultrasonication.
- Novel encapsulation of pigment using UV-curable resins has been developed.
- Thermal analysis and sedimentation provided supporting evidences for the encapsulation.
- Polyester acrylate oligomers and water soluble initiator stabilize the ink formulation.
- This method of modifying organic pigment to be used as UV-curable inks was effective.
