摘要： The present invention provides a water-base ink absorbing material which can quickly absorb a water-base ink and has an excellent fixativity of the drying water-base ink and on which print with a good definition can be achieved without inducing inconsistencies in color density and bleeding of ink.The ink absorbing material is prepared so as to satisfy the following requirements 1 through 3:1 the contact angle measured at ordinary temperature by the liquid drop method using water is 50 degrees or less;2 the wetting index measured in compliance with "Testing method of wettability of polyethylene and polypropylene films" defined by JIS-K-6768 is 40 dyn/cm or more; and3 the water vapor permeability P is 800-20000 g/m.sup.2 /24 h/0.1 mm, wherein P is obtained by converting the water vapor permeability P', measured in compliance with "Testing method for determination of the water vapor permeability of water vaporproof packaging materials (dish method)" defined by JIS-Z-0208 and in its temperature and moisture condition B, into the water vapor permeability at a thickness of 0.1 mm based on the following equationP=d.times.P'/0.1wherein d is a thickness (mm) of a specimen used for measurement of the water vapor permeability P'.
