Claim:
An ink-jet recording sheet comprising a reflective support having thereon a porous ink absorbing layer comprising a dye or a pigment, wherein the dye or the pigment is present in an amount of 0.01 to 200 mg per m 2 of the recording sheet; and a color difference ΔabL defined by the following formula is not more than 7: ΔabL=[(a 1 −a 2 ) 2 +(b 1 −b 2 ) 2 +(L 1 −L 2 ) 2 ] 1/2 wherein (L 1 , a 1 , b 1 ) and (L 2 , a 2 , b 2 ) each are a set of coordinates (L*, a*, b*) defined in a CIELAB color space and measured on a surface of the reflective support adjacent to the ink absorbing layer and on an outermost surface of the ink absorbing layer respectively, and a 2 is in a range of −2 to 2 and b 2 is in a range of −4 to 4.
