摘要:
The present invention provides a recording medium for sublimation type for heat-sensitive transfer recording process which comprises laminated paper as the substrate. In this laminated paper at least two cellulosic fiber papers are bonded together by adhesive agent and one side is coated with a dye accepting layer. Therefore, the recording medium for sublimation type for heat-sensitive transfer recording process which the present invention concerns uses, as the substrate, laminated paper in which cellulosic fiber papers are bonded together. This structure almost completely prevents curling of the recorded medium and also lowers the substrate production cost to achieve a low-cost recording medium and thereby greatly contribute to the expanded use of sublimation type recording printers.

Disclosed is a recording media for a sublimation-type heat-sensitive transfer recording process. The purpose of the present invention is to supply a recording media for a sublimation-type heat-sensitive process possessing an extremely high whiteness degree. The recording media comprises an image receiving layer composed of a dyeable resin which can be dyed by a sublimable dye; a crosslinking agent; and an anthraquinone based bluing agent. With the recording media for a sublimation type heat-sensitive recording process according to the present invention, a recording media having a high whiteness degree which does not turn yellow following curing can be obtained. As a result of the high whiteness degree of the foundation, this recording media is of an extremely high grade, and due to its extremely vivid recording image, it will be widely adopted and marketed in video printers.
