PROBLEM TO BE SOLVED: To obtain excellent printing characteristics after preserving under the atmosphere of high temperature and high humidity by a method wherein an ink receptive layer, consisting of the principal constituent of water-soluble resin or water absorbing resin, is provided on at least one side of a substrate sheet while the antistatic agent of phosfate sulfonic acid of aliphatic hydrocarbon is contained in the surface or the inside of the layer. SOLUTION: A normal substrate sheet can be used as it is as a substrate sheet 2 employed for a recording sheet 1 and there is no limit especially. An ink receptive layer 3, formed on at least one side of the substrate sheet 2, is constituted of the principal constituent of water-soluble resin or water absorbing resin while an antistatic agent of phosfate of aliphatic hydrocarbon or the sulfonic acid of aliphatic hydrocarbon is contained in the surface and/or the inside of the ink receptive layer 3. The antistatic agent is high in hydrophilic property and, therefore, is good in the drape with ink, excellent in water absorbing as well as drying property, and obtainable of proper expanding of dot whereby distinct picture without any spread of ink can be obtained and the deterioration of printing compatibility can not be seen even after preserving the same under the atmosphere of high temperature and high humidity. |
