Patent ID: 7563494

Claim:
An ink-jet recording material which comprises a light transmitting support, at least one ink-receptive layer provided on one surface of the support and at least one back-coating layer provided on the opposite surface of the support, wherein at least one of the back-coating layers contains inorganic fine particles having an average particle size of a primary particle of 5 to 50 nm and a binder, a void ratio of the layer is 70% by volume or less, and the light transmitting support has opacity regulated by JIS P8138A method of 60% or less, the ink-receptive layer comprises two or more layers, and an ink-receptive layer (A) near to the light transmitting support contains fumed silica having an average particle size of a primary particle of 10 to 30 nm and a hydrophilic binder and an ink-receptive layer (B) far from the light transmitting support contains alumina or alumina hydrate having an average particle size of a primary particle of 5 to 30 nm and a hydrophilic binder, and a weight ratio of the hydrophilic binder in the ink-receptive layer based on the amount of the inorganic fine particles is 5 to 30% by weight.
