    • 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. When used as an illumination signboard, moreover, the recording material affords superior images that are maintained when the illumination signboard is on or off.
    • 一种记录材料,包括在其上形成的基材和油墨接收层,其中所述基材具有38-200μm的厚度,所述油墨接收层是包含颗粒和树脂的多孔层,并且具有不小于40μm的厚度和 不大于105μm,并且其中所述记录材料具有不大于+ 10mm的卷曲值,以及包含基底和形成在其上的墨吸收层的记录材料,其中所述墨吸收层的表面强度不小于 超过80g重量/厘米。 由此获得的记录材料通过喷墨记录方法特别是使用油性油墨提供了具有极高耐水性和无渗色的图像的清晰记录。 即使在与湿度,温度等急剧变化相关联的严酷环境下,材料也难以卷曲,从而确保了记录材料的稳定的运输性,而不会由于与头部接触而引起麻烦。 此外,当用作照明招牌时,记录材料提供当照明招牌打开或关闭时保持的优质图像。
