记录介质
摘要：
本发明提供记录介质。记录介质依次包括基材、第一墨接收层、和作为最表层的第二墨接收层。第一墨接收层包含平均粒径为1.0μm以上的无定形二氧化硅。第二墨接收层包含胶体二氧化硅。第二墨接收层的表面的JIS B0601:2001中规定的粗糙度轮廓单元的均方根斜率RΔq为0.3以上。
摘要（英）：

A recording medium includes a substrate, a first ink-receiving layer, and a second ink-receiving layer serving as a top layer in this order. The first ink-receiving layer contains an amorphous silica having an average particle size of 1.0 [mu]m or more. The second ink-receiving layer contains a colloidal silica. The root-mean-square slope R delta q of roughness profile elements, provided in JIS B 0601:2001, of a surface of the second ink-receiving layer is 0.3 or more.
