Abstract:
An ink-jet recording sheet, comprising:(i) a support which is capable of absorbing water; and (ii) an ink absorptive layer, which has a void structure, including; (a) a first hydrophilic binder; and (b) inorganic particles having an average diameter of 3 to 200 nm; wherein the ink-jet recording sheet has a Q1 value of 15 to 35, and a Q1/Q2 value of 0.3 to 0.7; the Q1 value being a Bristow Test value (ml/m2) which is derived from a first transferred amount of a mixture solution of diethylene glycol/trietylene glycol monobutylether/water, at a respective weight ratio of 15:15:70, being in contact with a surface of the ink absorptive layer for 1.0 second; and the Q2 being a Cobb value (g/m2), and derived from a second transferred amount of the mixture solution in contact with the surface of the ink absorptive layer for 60 seconds.
