LEATHER FOR INK JET PRINTING AND ITS PRODUCTION

PROBLEM TO BE SOLVED: To obtain a leather for ink jet printing having no printing unevenness and a high dignity by providing a penetration control layer consisting of a water repellent and a binder resin on the surface of a leather and further laminating a coloring adjusting layer consisting of a cationic substance and the binder resin. SOLUTION: This leather is obtained as follows: at first, a penetration control liquid containing at least one kind of water repellent selected from the group consisting of a paraffin-based compound, an aluminum-based compound, a zirconium-based compound and an ethyleneurea and at least one kind of binder resin selected from the group consisting of an acrylic resin, an urethane-based resin and an acryl/urethane copolymer resin, and a coloring adjusting liquid containing a cationic substance, e.g. quaternary ammonium salt and the binder resin same as the above are respectively prepared. Then, the objective ink jet printing leather having water repellency of 50-80 points (according to JIS L-1092) is obtained by applying the penetration control liquid on the surface of natural or synthetic leather followed by drying, and then applying the coloring adjusting liquid thereon and drying.
