Abstract

Recording sheets used in printing applications such as ink jet printers should have the desirable characteristic of rapidly drying the ink image recorded on the sheet surface. Coated transparencies are particularly useful but he most widely used substrate is PolyEthylene Terephthlate (PET) which has a T, or glass transition temperature of about 75°C. When used in printers which utilize higher processing temperatures; e.g. drying temperatures of up to 120 - 14OoC, the substrate is heated to approximately the same temperature, resulting in deformation of the substrate during subsequent stripping and handling.

Recording sheets used in printing applications such as ink jet printers should have the desirable characteristic of rapidly drying the ink image recorded on the sheet surface. Coated transparencies are particularly useful but he most widely used substrate is
PolyEthylene Terephthlate (PET) which has a T, or glass transition temperature of about 75°C. When used in printers which utilize higher processing temperatures; e.g. drying temperatures of up to 120 - 14OoC, the substrate is heated to approximately the same temperature, resulting in deformation of the substrate during subsequent stripping and handling.

An improved transparency uses materials having a higher Tg to avoid the above-identified problem. For example, a suitable substrate materials include polysulfone with a Tg of about 190°C; polycarbonate, with a Tg of about 15OoC, or PolyEthylene Napthalate (PEN) with a Tg of about 120°C.
