Ink jet printing paper capable of providing, by using a low permeablity or a nonpermeable supporting sheet, a high surface glossiness and a high dot reproducibility of a silver halide photograph level, an excellent absorptivity of ink, and a high recording density, and preventing cockling by ink solvent, comprising the low permeablity or the nonpermeable supporting sheet, at least one ink receiving layer coated on the supporting sheet, and a luster layer coated on the ink receiving layer, the ink receiving layer in contact with the luster layer comprising pigment, as a main component, having a specific surface area-based mode diameter of pore distribution of 100 nm or less and an average secondary particle size of 1.3 &#x3bc;m or less, and the luster layer comprising pigment, as a main component, having an average primary particle size of 5 to 100 nm.

Ink jet recording paper

An ink jet recording sheet having an excellent jet ink-fixing property and heat-sealing property and capable of recording thereon ink images having excellent water resistance and light fastness has an ink receiving layer formed on a surface of a support sheet and including a binder and fine particles of a water-insoluble, amino group-containing resin having a total amine value of 5 to 500 and preferably a glass transition temperature of 15 to 250&deg; C.

Ink jet recording sheet

A recording material having a compression modulus of elasticity of 650 kgf/cm.sup.2 or less in the direction of the thickness thereof and exhibiting a maximum strain of 0.08 or more generated under pressure of 40 kgf/cm.sup.2 in the thickness direction of the recording material, can record thereon electro-coagulated ink images with high clarity and color density by electro-coagulation printing.
