Process for the production of record material |
摘要 |
Pressure- or heat-sensitive record material carries hydrated zirconia as a color developer material. The hydrated zirconia may be modified by the presence of compounds or ions of one or more multivalent metals. The record material may be made by forming an aqueous dispersion of hydrated zirconia, either formulating the dispersion into a coating composition and applying the coating composition to a substrate web or introducing the dispersion into a paper making stock and forming a paper web which incorporates hydrated zirconia as a loading, and drying the resulting coated or loaded web to produce the record material.
