The present invention aims to provide a water-absorbing resin crosslinking agent which is excellent in safety and which can effectively crosslink a water-absorbing resin at low temperatures to produce a water-absorbing agent having a high water absorption capacity. The present invention also aims to provide a water-absorbing agent produced by crosslinking a water-absorbing resin with the water-absorbing resin crosslinking agent, and a method for producing the water-absorbing agent. The present invention may include a water-absorbing resin crosslinking agent containing a halohydrin compound having one halohydrin group represented by the following formula (1) in its molecule: wherein A represents a single bond or an alkylene group; Rrepresents a hydrogen atom or an alkyl group; and X represents a chlorine atom or a bromine atom.

Water-absorbing resin crosslinking agent

An aqueous dispersion used for producing a conductive film is provided. The dispersion contains a complex of poly(3,4-dialkoxythiophene) and a polyanion, and is produced by polymerizing 3,4-dialkoxythiophene in an aqueous solvent in the presence of the polyanion by using peroxodisulfuric acid as an oxidizing agent or by using an oxidizing agent and an acid that is employed so as to lower pH of the reaction mixture.

A polysilane having excellent functionalities (e.g., solubility in a solvent and reactivity) is obtained by introducing a structural unit of the following formula (1) to a polysilane through a reaction of a dihalosilane having a Si&#x2014;H bond and adding a hydrosilylatable compound (e.g., a compound having a carbon-carbon unsaturated bond) to the Si&#x2014;H bond, 

Polysilane and polysilane-containing resin composition

A crosslinking agent for water-absorbing resins which comprises (A) at least one halohydrin compound selected between (A1) a first halohydrin compound having per molecule at least two halohydrin groups (D) represented by the general formula (I), wherein R represents hydrogen or alkyl and X represents chlorine or bromine and (A2) a second halohydrin compound having per molecule at least two halohydrin groups (D) represented by the formula (I) and having per molecule at least one ammonium group (M) represented by the general formula (II), wherein R 's each independently represents a C hydrocarbon group or benzyl.
