ABSTRACT:
An image-receptive heat transfer paper which includes: (a) a flexible cellulosic nonwoven web base sheet having top and bottom surfaces; and (b) an image-receptive melt-transfer film layer overlaying the top surface of the base sheet, which film layer is composed of from about 15 to about 80 percent by weight of a film-forming binder and from about 85 to about 20 percent by weight of a powdered thermoplastic polymer, wherein each of the film-forming binder and the powdered thermoplastic polymer melts in the range of from about 65 to about 180 degrees Celsius and the powdered thermoplastic polymer consists of particles which are from about 2 to about 50 micrometers in diameter. Alternatively, the image-receptive melt-transfer film layer is replaced with a melt-transfer film layer overlaying the top surface of the base sheet and composed of a film-forming binder which melts in the range of from about 65 to about 180 degrees Celsius, and an image-receptive film layer overlaying the melt-transfer film layer and composed of from about 15 to about 80 percent by weight of a film-forming binder and from about 85 to about 20 percent by weight of a powdered thermoplastic polymer, wherein each of the film-forming binder and the powdered thermoplastic polymer melts in the range of from about 65 to about 180 degrees Celsius and the powdered thermoplastic polymer consists of particles which are from about 2 to about 50 micrometers in diameter.
