摘要： A security feature is imparted to record material for use in pressure-sensitive copying paper systems by dyeing the surface sizing composition and/or other coatings present in the paper and then applying the dyed composition or coating in a manner such as to produce an uneven coating pattern, for example a film-split pattern. The dye accentuates the coating pattern and produces a visual effect which is difficult to replicate without access to a papermaking or paper coating machine, and which has a distinguishably different appearance from that of the opposite surface of the reccord material. The invention is particularly suited for use with a Billblade coater which applies a dyed surface sizing composition to one surface of the paper and a pigment coating to the other surface or with a metered size press coater.
