  • Patent number: 6605337
    Abstract: A recording material comprising a substrate and an ink receiving layer formed thereon, wherein said substrate has a thickness of 38-200 &mgr;m, said ink receiving layer is a porous layer comprising particles and a resin and has a thickness of not less than 40 &mgr;m and not more than 105 &mgr;m, and wherein the recording material has a curl value of not more than +10 mm, and a recording material comprising a substrate and an ink absorption layer formed thereon, wherein the ink absorption layer has a surface strength of not less than 80 g weight/cm. The recording material thus obtained affords sharp recording of images having extremely high water resistance and free of bleeding by the ink jet recording method particularly using oily ink. The material hardly curls even under severe environment associated with radically changing humidity, temperature and the like, thereby ensuring stable transportability of the recording material without trouble caused by being in contact with a priting head.
