摘要:
A pressure-sensitive carbonless transfer sheet comprising a paper substrate having a front and back surface and a coating compositon adhered to at least one of the front and back surfaces of the paper substrate. The coating composition is set to a flexible, tack-free coat, and the coating composition includes a solvent free non-aqueous hot melt suspending medium which is characterized by being substantially water insoluble, being characterized by the presence of one or more functional groups selected from the group consisting of: carboxyl, carbonyl, hydroxyl, ester, amide, amine, heterocyclic groups and combinations thereof to impart polarity thereto and having a melting point of from about 60.degree. C. to about 140.degree. C. and a melting point range of less than about 15.degree. C. In addition the coating composition includes an encapsulated, chromogenic material which is substantially dispersed therein, the hot melt suspending medium being compatible with the color forming characteristics of the capsular chromogenic material. This invention further includes a liquid chromogenic coating compositon which comprises a hot melt suspending medium in combination with a microencapsulated chromogenic material. The chromogenic material is a color precursor of the electron donating type which is mixed with a carrier oil to form an oil solution of the chromogenic color precursor material which is then combined with one or more wall forming compounds.
