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. The ink includes from about 25 to 35% of a non-volatile oil, 25 to 35% of an acidic color developer, 20 to 50% filler, and 4 to 15% dispersed wax particles, all percentages by weight.
