Ink jet recording sheet and ink jet recording method |
(57) A recording medium is provided which enables a good print to be formed on both surfaces
thereof and, when printing on one surface of the recording medium is performed under
conditions different from that in the printing on the other surface of the recording
medium, causes neither curling nor strike through of the print. The recording medium
comprises: a substrate having two faces; and an ink-receptive layer or a coat layer
provided on both faces of the substrate to form a first sruface and a second surface
opposite the first surface, wherein when a droplet of an ink in an identical amount
is deposited onto the first and second surfaces of the recording medium, the diameter
of a dot formed on the first surface is different from that of a dot formed on the
second surface.
