Abstract
The invention provides a recording sheet having an ink-receiving layer, which comprises a substrate sheet and an ink-receiving layer formed thereon, said ink-receiving layer comprising oxide particles, wherein the ink-receiving layer has pores having a diameter in the range of 3.4 to 2,000 nm, the pore volume of pores having a diameter of 3.4 to 30 nm is in the range of 0.2 to 1.8 ml/g, and the pore volume of pores having a diameter of 30 to 2,000 nm is in the range of 0.1 to 1.5 ml/g. It is preferable that the oxide particles have an average particle diameter of 2 to 1,000 nm and are a mixture of hydrophobic oxide particles and hydrophilic oxide particles. This recording sheet shows sufficient strength, has excellent printability such that images of uniform density and high sharpness can be printed thereon without bleeding, and is excellent in water resistance, weathering resistance and fading resistance.
