摘要:
An ink-receiving layer has a bilayer constitution, which is formed by sequentially laminating a lower layer and an upper layer on a support. The upper layer contains alumina having an average pore diameter of less than 5 nm (alumina A) and alumina having an average pore diameter of 5 nm or more (alumina B) in a weight ratio of (alumina A):(alumina B)=100:0 to 70:30; the lower layer contains the alumina A and the alumina B in a weight ratio of (alumina A):(alumina B)=0:100 to 50:50; and the thickness ratio of the upper layer to the lower layer is as follows: (upper layer):(lower layer)=2:1 to 5:1.
