ABSTRACT:
A self-contained pressure-sensitive record material comprising a substrate and a coating thereon of an interspersed mixture of pressure-rupturable capsules of an oily solvent solution of a substantially colorless basic chromogenic material and capsules of solid co-reactant acidic resin particles, said co-reactant acidic resin being capable of producing a color upon contact with the chromogenic material. The capsule mixture is applied to the substrate in a single coating step, resulting in a greater production efficiency. The resulting record material provides better imaging characteristics with less print bleed than self-contained systems known in the prior art.
