ABSTRACT:
The invention relates to a recording material for the inkjet process, having a sheet-like substrate layer and at least one porous recording layer which is arranged on at least one side of the substrate layer and contains a binder combination comprising a film-forming plastics dispersion and a film-forming water-soluble polymer and from 30 to 90 k by weight, based on the dry recording layer, of an organic pigment which consists of porous particles or of primary particles which form porous agglomerates and has a mean pore diameter of from 0.1 to 0.5 .mu.m, an internal pore volume of from 1.0 to 4.0 cm.sup.3 /g, an oil absorption (DBP) of from 200 to 350 ml/100 g and a mean diameter of the porous particles or of the porous agglomerates of from 1 to 30 .mu.m, the ratio of pigment to binder being from 0.5:1 to 2:1. The recording material is particularly suitable for use with pigmented ink.
