ABSTRACT:
Water-stable phenol-amine complexes of limited water solubility for use in a thermal-sensitive paper coating containing a chromogenic compound.
The complexes contain phenolic hydroxy groups and amine groups in an essentially 2:1 ratio, the amines being low boiling amines. The phenols are of the class capable of forming amine complexes having a ratio of two hydroxyl groups for each amine group. The resulting coating compositions effectively resist premature color formation during formulation, and the coated papers produced exhibit enhanced stability.
