  • Method for paper treatment
    Patent number: 8822017
    Abstract: A surface treatment method of oil contaminated xerographic prints which increases the surface energy of the print to levels close to the values corresponding to the original uncontaminated paper. Subjecting the contaminated surface to both ultraviolet (UV) radiation and ozone can change the chemical structure of the surface of the paper in such a way that a highly polar surface is created as a consequence of this treatment, leading to enhanced adhesion properties of the xerographic print.

  • Coatings for ink jet print head face
    Patent number: 8692011
    Abstract: A novel composition for use as a print head face plate coating. In particular, the coating comprises siloxyfluorocarbon (SFC), which is composed of networked precursors containing reactive siloxane groups attached to fluorocarbon chains. The present SFC coatings can be used to produce a surface whereby solid ink and ultraviolet (UV) curable inks do not adhere when applied at elevated temperatures and over an extended period of time. The advantages of the present coating are fewer print head related defects, and longer front face life.
