Abstract: A CF ink and process which can be applied to a support sheet by standard transfer-litho press is provided. The nonvolatile printing ink which is capable of color development may be used to produce a CF carbonless copy sheet, or, in combination with a high solids, aqueous-based CB ink, to produce a CFB carbonless copy sheet.
