ABSTRACT:
The object of the present invention is to provide a more practical liquid-absorbing substrate capable of absorbing not only water but also alcohols, wherein liquid absorbency and gel properties of the substrate can be easily controlled.Namely, the present invention relates to a liquid-absorbing substrate containing:(A) a product obtained by hydrolysis and polycondensation of a compound represented by the formula (I)in-line-formulae description="In-line Formulae" end="lead"?(R1)nM(X)m-n  (I)in-line-formulae description="In-line Formulae" end="tail"?(wherein, R1represents a hydrogen atom, C1-C6alkyl, or C2-C6alkenyl; M represents a metal atom; X represents a hydrolyzable group; m represents the atomic valence of M; and n represents an integer of 0 or 1) in a solvent in the presence of a catalyst; and(B) a cellulose derivative having a mass-average molecular weight of 1×105to 5×106.
