Dependent claims

An inkjet recording medium comprising:

a water-impermeable substrate, and a first ink-receiving layer containing kaolin and a second ink-receiving layer containing fumed silica which are provided on the water-impermeable substrate in this order from a water-impermeable substrate side,
wherein at least the first ink-receiving layer further contains a boron compound, and a content ratio (% by mass) of boron in a total solid content of the first ink-receiving layer is higher than a content ratio (% by mass) of boron in a total solid content of the second ink-receiving layer.

A method of manufacturing an inkjet recording medium, the method comprising:

forming ink-receiving layers by simultaneously multilayer-coating, onto a water-impermeable substrate, at least a first coating liquid containing kaolin and a second coating liquid containing fumed silica in this order from a water-impermeable substrate side,
wherein at least the first coating liquid further contains a boron compound, and a content ratio (% by mass) of boron in a total solid content of the first coating liquid is higher than a content ratio (% by mass) of boron in a total solid content of the second coating liquid.
