Abstract
A recording sheet adaptable to print an image using pigment ink, on which a smear is hardly generated, is provided. A recording sheet includes an ink permeable layer prepared by adding 3-30 parts by weight of a nonionic surfactant including an amine compound as a main component to 30 parts by weight of a water-insoluble component including an inorganic filler and a binder as main components. Ink applied on such an ink permeable layer is directly absorbed into the layer in a depth direction without dispersing in a lateral direction. Therefore, any smear (banding) is hardly generated on a printed image formed on the recording sheet using ink.
