The present invention provides a method of producing a tetracyanoborate-containing ionic compound in a milder condition more efficiently and less expensively than conventional methods, and a tetracyanoborate-containing ionic compound having a reduced content of impure components. An ionic compound of the present invention is represented by the following general formula (I), has a content of fluorine atom-containing impurities of 3 mol % or less per 100 mol % of the ionic compound, and a method for producing an ionic compound represented by the general formula (I) of the present invention comprises a step of reacting starting materials containing a cyanide and a boron compound. (In the formula, Ktdenotes an organic cation [Kt]or an inorganic cation [Ke]; and m denotes an integer of 1 to 3.)

Ionic compound, method for producing the same, and ion-conductive material comprising the same

A borate for a near-infrared ray absorption material, having an anion represented by the formula (1): [BRR](wherein Rrepresents an aryl group having an electron withdrawing group; Rrepresents an organic group, a halogen group or a hydroxyl group; and m is an integer in the range of 1 to 4) is provided. The borate of the present invention enables to improve durability, in particular, heat resistance and moisture resistance of a near-infrared ray absorbing dye.

The present invention has an object to provide a transparent resin material having a low water absorption ratio without deteriorating various properties such as transparency which transparent resin has and also having a controllable refractive index. The present invention provides a transparent resin material containing a polymer capable of forming a formed product having transparency, wherein the transparent resin material comprises a fluorine atom-containing polymer and/or compound and contains 0.3 to 35% by weight of a fluorine atom in 100% by weight of the formed product.

Transparent resin material

The present invention has an object to provide a fluorine-containing compound which can be used for applications such as additives making a transparent resin material low in a water absorbing ratio and high in water repellency without deteriorating of various properties such as transparency which the transparent resin material has, a fluorine-containing ester compound which is superior in properties such as heat resistance and low moisture(water) absorption property and can be suitably used in various fields such as a material for electronic information, a material for precision instruments and an optical material, a fluorine-containing aryl ester polymer, methods of producing the same. The present invention provides a fluorine-containing compound represented by the following formula (1): 

Fluorine-containing compound

Compound fine particles include inorganic fine particles and an organic polymer bound to surfaces of the inorganic fine particles, and have an average particle diameter of 5 to 200 nm and a particle diameter variation coefficient of 50% or less. The compound fine particles are obtainable by hydrolyzing and condensing an organic polymer, wherein the organic polymer has, per molecule, at least one polysiloxane group containing at least one Si--OR.sup.1 group, wherein R.sup.1 denotes a hydrogen atom, an unsubstituted or substituted alkyl group, or an unsubstituted or substituted acyl group. A compound fine particle dispersion includes the compound fine particles and a dispersion medium. A composition for forming a film includes this dispersion.
