PURPOSE:To improve the anti-chemical and anti-abrasion property, by forming a double layer protection layer on a diazonium salt containing layer and a coupler containing layer and mixing a specific resin into the coupler containing layer and respective protection layers. CONSTITUTION:A diazonium salt containing layer, a coupler containing layer and protection layers I, II are laminated sequentially onto a basic material. Polyester resin and/or polyurethane resin is contained in the coupler containing layer and the protection layer I. Polyurethane resin and/or acrylic resin is contained in the protection layer II. Preferably, the polyester resin and the polyurethane resin to be mixed into said coupler containing layer and the protection layer I have one or more kind of functional groups selected from carboxyl group, carboxyl base, sulfonic acid group, sulfonic acid base, hydroxyl group, epoxy group, unsaturated group and amino group in the side chain or the main chain of the molecular structure. |
