  • Inkjet printing paper
    Patent number: 6616808
    Abstract: An inkjet printing paper of noncoated type, in which the feathering is prevented and the conveyability is improved. This inkjet printing paper comprises calcium carbonate as its filler wherein the filler contains ash of 10 to 30 weight % as defined in JIS P 8128 and wherein the paper has Stockigt sizing degree of 0.001 to 0.05 sec/g/m2 according to JIS P 8122. Further, in this paper, X-ray image obtained from area-analysis with an energy-distributed X-ray microanalyzer for the surface of the inkjet printing paper, the area of white part, which indicates the presence of calcium, is 3 to 40% related to the total area of the X-ray image.
