Abstract:
An ink-jet recording material comprising a polyolefin resin-coated paper support and at least one ink-receptive layer containing fumed silica and a water-soluble polyvalent metallic compound provided on the support, wherein a surface of the support on which the ink-receptive layer is provided has been subjected to work, by using a cooling roll with a surface having fine unevenness with an average depth at the surface of 0.05 to 0.7 &mgr;m and an average pitch of 0.1 to 100 &mgr;m, into slightly rough surface with a center surface average roughness SRa represented by the following formula of the support being 0.11 to 0.50 and 75 degrees specular glossiness according to JIS P 8142 is from 30% to less than 70%, SRa=1Sa&it;&Integral;oWx&it;&Integral;oWy&it;&LeftBracketingBar;f&it;(X,Y)&RightBracketingBar;&it;â€ƒ&it;&dd;X,&dd;Ywherein Wx represents a length of a sample surface area to an x-axis direction; Wy represents a length of the sample surface area to a y-axis direction; and Sa represents an area of the sample surface area.
