Provided is a substrate with a film formed thereon, wherein a film which contains a compound having a structural unit derived from a monomer and an adsorption group is formed on at least a part of a metal surface present on a substrate, and the specific gravity of the metal is not more than 19.30 g/cm3.
B32B 15/08 - Layered products essentially comprising metal comprising metal as the main or only constituent of a layer, next to another layer of a specific substance of synthetic resin
C08F 292/00 - Macromolecular compounds obtained by polymerising monomers on to inorganic materials
C09D 133/04 - Homopolymers or copolymers of esters
C09D 201/02 - Coating compositions based on unspecified macromolecular compounds characterised by the presence of specified groups

Provided is an absorbent body that, for example, in a case where the absorbent body has been used in an absorbent article, such as a thin disposable diaper, having an absorbent body with a low proportion of fiber material (hydrophilic fibers) such as pulp, enables the absorbent article such as a disposable diaper to have an improved liquid trapping function on second and subsequent urinations over the conventional ones and particularly to have an increased amount of liquid trapped under load on the second and subsequent urinations over the conventional ones. Also provided is a water-absorbing resin that is used in the absorbent body and has an increased absorption capacity under load on the second and subsequent urinations over the conventional ones.
