  • Publication number: 20080233291
    Abstract: The invention is a method for depositing an inorganic layer to a laser-induced thermal transfer layer, and to a deposited transfer layer made by the method. In one embodiment, the transfer layer is disposed on a receiver element comprising a glass substrate with black matrix for a color filter comprising red, blue and green transparent pixels formed by laser-induced thermal transfer, and the inorganic layer is an indium-tin oxide transparent electrode grounding layer. The method for depositing the inorganic layer to the transfer layer comprises exposing a laser-induced thermal transfer layer to ultraviolet radiation to produce an exposed transfer layer, treating the exposed transfer layer with a cleaning fluid to produce a cleaned transfer layer, and depositing an inorganic layer in contact with the cleaned transfer layer to produce a deposited transfer layer.

  • Patent number: 7361437
    Abstract: The invention provides a thermal transfer donor element comprising a support layer and a transfer layer supported by the support layer and comprising a binder containing carboxylic acid groups. The transfer layer includes an organic compound containing a plurality of hydroxyl groups with a hydroxyl group concentration of less than 18 mM/g and at least one connecting group, wherein the organic compound is free of any N,N-bis-(2-hydroxyethyl)amide and any rosin ester. In another embodiment, a method of using the donor element is provided, particularly in the manufacture of a color filter.
