    Abstract: A TEMPERATURE-RESPONSIVE DISPLAY DEVICE OR COMPOSITION, COMPRISING MESOMORPHIC ("LIQUID CRYSTAL") MATERIALS(S) CONTAINED IN MINUTE CAPSULES AS THE TEMPERATURERESPONSIVE COMPONENT, IS PROVIDED. THE MINUTE CAPSULES, WHEN PLACED IN HEAT-CONDUCTIVE RELATION WITH A HEAT SOURCE TOGETHER WITH AN ASSOCIATED THERMAL GRADIENT PATTERN TO BE DISPLAYED, EXHIBIT AN IRIDENSCENCE INDICATIVE OF A CERTAIN CHARACTERISTIC TEMPERATURE RANGE, WHICH TEMPERATURE RANGE VARIES ACCORDING TO THE TYPES AND MIXTURES OF MESOMORPHIC MATERIALS AFFORDS PHYSICAL AND CHEMICAL PROTECTION FROM VARIOUS KINDS OF DEGRADATION AND ALLOWS THEIR USE IN PRACTICAL AND EFFICIENT THERMAL-GRADIENT DISPLAY SYSTEMS.

    Abstract: An ink supply transfer medium is disclosed. The medium is of such a construction that marking pressure causes a transfer of colored ink material to any surface with which the medium is then in contact. The medium, usually in sheet form, includes a substrate and an ink supply layer with a dye decoloring layer located therebetween. The ink supply layer includes all of the reactive colorless components required to yield a colored marking ink but the components are separated and provide a potential colored mark available on occasion of component release. The decoloring layer includes a continuous polymeric barrier film with a dye decoloring reactant homogeneously dispersed therethroughout. Prior to application of marking pressure, the sheet does not include colored ink and does not appear to include colored ink transfer capabilities. After application of marking pressure, colored ink is produced and transferred and there is no trace of residual, untransferred, colored ink on the sheet.
