An electrolyte composition includes: a sulfonylimide compound represented by the following general formula (1) as an electrolyte salt; and an amidosulfuric acid component.LiN(XSO)(XSO)  (1)

Electrolyte composition, solvent composition, non-aqueous electrolyte, and use thereof

The present invention provides an electrolyte composition that provides better charging/discharging performance when used in a cell than a conventional electrolyte composition. The present invention relates to an electrolyte composition containing an alkali metal salt, at least one polymer selected from the group consisting of a polyether polymer, a (meth)acrylic polymer, a nitrile polymer, and a fluoropolymer, and an ion dissociation accelerator. The composition has an alkali metal salt concentration of 1.8 mol/kg or higher.

A method for dehydrating a porous cross-linked polymer conveniently to a low final water content is provided. A porous cross-linked polymer sheet is produced by a method which comprises causing a porous cross-linked polymer obtained by forming and polymerizing a water-in-oil type higher internal phase emulsion to be dehydrated by the use of non-woven fabric rolls furnished with an aspiration mechanism. Properly in this case, the porous cross-linked polymer is subjected to preliminary squeezing. In accordance with the present invention, a porous cross-linked polymer abounding in a water absorbing property to be dehydrated to a low final water content with a small number of rolls.

Method for production of porous cross-linked polymer sheet

A method for producing a porous cross-linked polymer sheet capable of slicing quickly is provided. This method comprises a step for obtaining a porous cross-linked polymer by forming and polymerizing an HIPE, a step for dehydrating the porous cross-linked polymer, and a step for subsequently slicing the dehydrated porous cross-linked polymer. According to this invention, by performing the step of dehydration prior to the conventional step of slicing, it is made possible to prevent the porous cross-linked polymer from adhering to the blade and the guides provided for a slicer, and allow the slicing to be attained quickly. By removing the salt from the polymer, it is further made possible to prevent a production device from gathering rust and the porous cross-linked polymer from permitting adhesion of rust thereto.

The photo-curable liquid solder resist ink composition of the present invention mainly comprises a photo-polymerizable resin having sufficient molecular weight and (meth)acryloyl groups which are imparted by both of introduction of (meth)acryloyl groups into a novolak-type epoxy resin having 4 or more of benzene nuclei and polymerization using a chain-extension agent. The composition is useful for a photo-curable type resist, since it can produce a coated film excellent in tack free characteristic and resolution, and can produce a cured film excellent in heat resistance, adhesiveness, and chemical resistance. In addition, by reacting with an acid anhydride, development with alkalis becomes possible.
