Estimating the term…
An ink-jet recording material having on a support at least the outermost ink-receiving layer and a lower ink-receiving layer, with the outermost ink-receiving layer containing as main constituents a binder and a pigment having an average particle size of 30 to 500 nm and being constituted so that all constituents contained therein show a pH value of from 6.5 to 10 as a slurry solution prepared by dispersing them homogeneously in water in a total concentration of 10% by weight, thereby providing fast images of high quality equivalent to those obtained by silver halide photography and graphic arts when multiple color printing is done thereon with an inkjet color printer using water-based pigment ink.
An ink-jet recording material for pigment ink which has on a support at least two ink-receiving layer including the outermost ink-receiving layer and a lower ink-receiving layer, said outermost ink-receiving layer containing as main constituents a binder and a pigment having an average particle size of 30 to 500 nm and being constituted so that all constituents contained therein show a pH value of from 6.5 to 10 as a slurry solution prepared by dispersing them homogeneously in water in a total concentration of 10% by weight.
