METHOD FOR MANUFACTURING INK ABSORPTIVE PRINT MEDIUM USING CATIONIC POLYVINYL ALCOHOL COATING SOLUTION AND INK ABSORPTIVE PRINT MEDIUM THEREBY

摘要

PURPOSE: A method for manufacturing an ink absorptive print medium and an ink absorptive print medium are provided to enhance a quality such as an ink absorbency and a weatherability. CONSTITUTION: The method for manufacturing an ink absorptive print medium comprises the steps of: (P1) forming a coating layer by applying a water dispersible or colloid solution based on a cationic alumina or cationic alumina hydrate on a substrate; (P2) drying or semi-drying the formed coating layer; and (P3) applying a cationic polyvinyl alcohol aqueous solution to the dried or semi-dried coating layer. The substrate is paper. The method further comprises (P4) casting the coating layer with the cationic polyvinyl alcohol applied on.
