Disclosed is a pressure-sensitive record unit which comprises a top sheet having coated on the underside thereof solid color former material and a bottom sheet having coated on the upper side thereof a coating comprising solid color developer material and microcapsules containing a liquid solvent for the color former. Such a record unit makes possible the unexpectedly efficient utilization of the color former material. It furthermore permits the printing application of some of the components, resulting in even more efficient utilization of color former material and elimination of undesirable side effects of printed record units taught in the prior art.
