Abstract:
1. An ink jet recording sheet for use with aqueous ink comprising a support having a porous ink receiving layer thereon, wherein the porous ink receiving layer is formed from an aqueous coating solution and comprises inorganic particles, a cross-linked hydrophilic binder and a compound having a plural number of nonaromatic carbon-carbon unsaturated bonds in a molecule, wherein the compound is polybutadiene having a number average molecular weight of 500 to 10,000, the inorganic particles are silica particles having a mean particle diameter of 3 to 200 nm, and the compound having a plural number of nonaromatic carbon-carbon unsaturated bonds in a molecule is added dispersed as minute oil droplets in the aqueous coating solution for forming the porous ink receiving layer.
