Abstract:
1. An inkjet recording medium comprising: a support; at least one ink receiving layer formed on one surface of the support, containing at least fine particles and a water-soluble resin; and a back coat layer that is formed on the other surface of the support, the back coat layer being formed by a coating liquid essentially consisting of a) a resin, a surfactant and water, or b) a resin and water, the resin having a stress at break of from 30 to 100 MPa and an elongation at break of from 2 to 40% GL, wherein: a static friction coefficient between an uppermost surface of the ink receiving layer side of the support and the uppermost surface of the back coat layer side of the support is in the range of from 0.46 to 0.77, and wherein the following equation is satisfied: wherein A is a static friction coefficient between the uppermost surface at the back coat layer side of the support and a metal roller onto which wear-resistant particles are adhered; B is an amount of deformation of the overall layer(s) on the back coat layer side of the support measured in μm; and C is an overall rigidity of the layers including the support, the ink receiving layer and the back coat layer measured in mM·n and wherein A, B and C are within the ranges of 0.84>A>0.44, 32>B>20 and 5>C>2, respectively.
