Abstract
A printing composition constructed from a printing layer and a blotting layer. The printing layer has a plurality of pores connecting the top and bottom surfaces thereof and is adapted for accepting ink that is retained in the pores. The blotting layer has a top surface that is in contact with the bottom surface of the printing layer. The blotting layer is constructed from a material that has an affinity for the ink that is less than that required to remove the ink from the pores if the pores are not filled with the ink. The printing layer may be constructed from a plastic that has been coated with a surfactant that renders the sides of the pores hydrophilic. The blotting layer may be constructed from a sheet of plastic having pores therein. The blotting layer may also be constructed from a sheet of paper. In the preferred embodiment of the present invention, the printing layer is an electret.
