ABSTRACT:
A high solids contents, aqueous-based, self-contained printing ink is provided including, a non-volatile diluent, an acidic color developer, a binder, and a water soluble surfactant which is compatible with the binder in the ink, but which is incompatible with the binder when the ink has dried. The high solids, self-contained printing ink further includes microcapsules containing a dyestuff precursor that is capable of reacting with the acidic color developer to form a color. The ink may be used to prepare self-contained carbonless copy sheets.
