  • Patent number: 9920481
    Abstract: A lightweight digital printing medium has a basis weight of less than 100 grams per square meter and includes a base paper. The base paper includes a fiber mixture of hardwood pulp and softwood pulp where at least 5% by weight of total fiber in the fiber mixture is bleached, chemi-thermo-mechanical pulp. An internal sizing agent for neutral or alkaline conditions and a wet-strength agent that is a thermosetting resin are mixed with the fiber mixture. An amount of the wet-strength agent added to the fiber mixture is at least 0.1% total dry weight of the base paper.

  • Patent number: 9435079
    Abstract: An uncoated recording medium includes a blend of hardwood fibers and softwood fibers. The total fiber content is at least 80 wt % of a total wt % of the uncoated recording medium. A filler is present in the uncoated recording medium in an amount ranging from about 3 wt % to about 10.2 wt % of the total wt % of the uncoated recording medium. The uncoated recording medium has i) a weight ranging from about 50 g/m2 to about 70 g/m2, and ii) a machine direction Lorentezen & Wetter 5 degree bending stiffness ranging from about 0.19 mNm to about 0.27 mNm and a cross direction Lorentezen & Wetter 5 degree bending stiffness ranging from about 0.09 mNm to about 0.12 mNm, and iii) an ISO brightness of at least 86.
