  • Microporous photo glossy inkjet recording media
    Patent number: 6979481
    Abstract: The present invention provides microporous photo quality glossy inkjet receiving media comprising a substrate, an absorbent basecoat layer, and an ink-receptive topcoat. The absorbent basecoat layer is primarily a combination of pigment and binder, and may include deformable particles, such as core-shell polymeric pigments. The ink-receptive topcoat is composed primarily of alumina hydrate, gelatin, and a water-insoluble cationic polymer. The present invention also provides a method for increasing the gloss and surface smoothness presented by the topcoat of a printing medium by including deformable particles in an underlying basecoat followed by calendering of the printing medium. Further, the present invention provides combination matte and gloss inkjet printing media, comprising matte basecoats at least partially coated with the aforementioned ink-receptive topcoat.
