ABSTRACT:
An image receiving sheet for use in a thermal image transfer recording system, has an absorption coefficient (Ka) of 0.05 to 0.75 ml/m.sup.2 .multidot.(msec).sup.1/2 with respect to extra pure liquid paraffin at a pressure of 0.1 MPa when measured by the Bristow's Method (J.TAPPI No. 51-87). As such an image receiving sheet, an image receiving sheet having a recording surface with the product of (a) the absorption coefficient (Ka) with respect to the liquid paraffin (extra pure reagent) measured by the Bristow's Method (J.TAPPI No. 51-87) at a pressure of 0.1 MPa and (b) the gradient (fc) of a linear portion of a load curve obtained by a three-dimensional surface roughness analysis being in the range of 0.5 to 6.0 can be used. An image receiving sheet having a recording surface with the amount (V) of an ink transferred to the receiving sheet during 100 msec being in the range of 2.3 to 11.5 ml/m.sup.2 can also be used. The amount (V) is obtained from (a) the absorption coefficient (Ka) and (b) the surface roughness index (Vr) of the recording surface, which are measured by the Bristow's Method (J.TAPPI No. 51-87) at a pressure of 0.1 MPa, with respect to the liquid paraffin (extra pure reagent).
