摘要： AMMONIA IS EMPLOYED TO IMPART A BASIC PH AND TO DISPERSE AN AQUEOUS SUSPENSION OF A NORMALLY ACIDIC. ADSORPTIVE DYE-SENSITIVE PIGMENT DURING THE PREPARATION OF AN AQUEOUS COATING COMPOSITION CONTAINING THE PIGMENT. SHEETS COATED WITH THE AMMONIA-TREATED COATING COMPOSITION ARE USED AS RECEIVING SHEETS FOR PRINTING WITH TRANSFER SHEETS CONTAINING ENCAPSULATED COLOR-REACTANT DYE MATERIAL.

摘要： This application is directed to the preparation of receiving sheets for printing with transferable colorless, color-forming dye material in which the sensitive pigment that converts the colorless, color-forming dye to colored form is a hydrated aluminum silicate obtained by the hydrothermal treatment of dehydrated kaolin clay. The application discloses the discovery that a high surface area, partially hydrated metakaolin pigment that is capable of producing an intense nonfading printed image may be obtained by terminating the hydration of the dehydrated clay prior to the time when the resulting hydrated aluminum silicate would possess the maximum surface area that could be obtained by the hydrothermal treatment.
