Abstract: PROBLEM TO BE SOLVED: To provide a method which can efficiently produce a polymer/metal cluster composite with a simple process from easily available raw materials. SOLUTION: A solid polymer compound such as a polyamide such as nylon 6, polyester such as polyethylene terephthalate, a condensation type resin such as a polycarbonate and an epoxy resin, an addition polymerization type resin such as a polystyrene, a polypropylene and polyvinyl alcohol or a solid polymeric compound of a natural polymeric compound such as cellulose acetate, is brought into contact, at a temperature of not lower than the glass transition temperature, with the vapor of a heavy metal compound to prepare the polymer/ metal cluster composite.

Abstract: PROBLEM TO BE SOLVED: To rapidly and efficiently obtain high-grade gold by dissolving an iodine of an alkali metal, etc., and the indine alone in a volatile org. solvent, then dissolving gold contg. impurities under heating into this soln., distilling off the org. solvent, precipitating and separating the gold and subjecting the gold to a washing treatment with the org. solvent. SOLUTION: The iodides of alkali metals and alkaline earth metals; for example, lithium iodide, calcium iodide, etc., are used as the iodide. Nitriles and lower alcohols are preferable as the org. solvent in the sense that the dissolution rate of the gold is high and the distillation off is easy as these materials are volatile and dissolve both the iodide and iodine alone to be used. If the gold precipitated by decantation is separated by using the org. solvent distilled off and recovered in the previous stage at the time of washing the residue contg. the gold after the precipitation of the gold, the supernatant liquid thereof is usable again for the dissolution of the gold. Then, the org. solvent is not disposed as waste.

Abstract: PROBLEM TO BE SOLVED: To efficiently obtain the subject complex exhibiting high threeorder nonlinear optical characteristics and useful as a nonlinear optical material by a simple operation by absorbing iodine vapor into a solid complex containing an iodogold[I] anion. SOLUTION: (A) A solid complex composed of (i) an iodogold[I] anion and (ii) a quaternary ammonium ion, preferably a complex represented by formula I (R to R are each a hydrocarbon) is brought into contact with iodine vapor to absorb iodine and excess iodine is released in the absence of iodine vapor to provide the objective complex of formula II. Furthermore, release of excess iodine is preferably carried out by allowing the complex to stand in the air.

Abstract: PURPOSE:To easily dissolve many metals by bringing metals into contact with an organic solvent in the presence of quaternary ammonium trihalide obtd. by the reaction between a cationic surface active agent and halogen simple substance. CONSTITUTION:A cationic surface active agent and halogen simple substance expressed by a general formula [RidenticalN-R'] .X (in the formula, RidenticalN denotes trialkylamino groups or pyridyl groups, R' denotes 6 to 22 C alkyl groups and X denotes halogen atoms) are dissolved in liquid hydrocarbon, and they are brought into reaction. By bringing metals into contact with the formed quaternary ammonium trihalide shown by a general formula [RidenticalN-R'] .X (in the formula, RidenticalN denotes trialkylamino groups or pyridyl groups, R' denotes 6 to 22 C alkyl groups and X denotes halogen atoms) and an organic solvent, the metals are converted into compounds easy to dissolve and are easily dissolved.

Abstract: PURPOSE:To readily and completely decolor a colored formed fiber product colored with fine gold particles by treating the aforementioned formed product in water or an organic solvent liquid containing a simple halogen substance or soluble halogenate. CONSTITUTION:A formed fiber product colored with fine gold particles is dipped and treated in water or an organic solvent containing a simple halogen substance (e.g. bromine or iodine) or a soluble halogenate (e.g. potassium iodide, calcium bromide or ammonium bromide), e.g. a solution of methanol, ethanol or acetone, readily and completely decolored at a low cost. Decoloring can be carried out many times according to the above-mentioned method to perform redyeing.

Abstract: PURPOSE:To economically and safely dissolve metals by bringing the metals into contact with a quaternary ammonium compound represented by a specific formula and halogenated hydrocarbon. CONSTITUTION:Metals are brought into contact with a quaternary ammonium compound represented by a formula I and halogenated hydrocarbon. Further, the metals are brought into contact with a polar solvent. In the formula I, at least one among R1, R2, R3, and R4 is means chloride ion or bromide ion. By this method, the application of this method to many metals can be attained.

Abstract: PURPOSE:To obtain a beautiful purple colored free from change of color and fading by treating solid surface with an aqueous solution of gold salt, irradiating the whole face of the surface with light rays or through an image carrier and removing the gold salt on unexposed part. CONSTITUTION:Solid surface of silk fiber, cellulose fiber subjected to cationic treatment or solid material coated with gelatin is treated with an aqueous solution of a gold salt such as chloroauric acid, sodium chloroaurate or potassium tetracyanoaurate. Then the whole face of the solid surface is irradiated with light rays to seal the metal salt to the whole face. Light rays of negative image are projected to the surface by using a proper image carrier to partially form gold fine particles, the gold salt on an unexposed part is eluted and removed to provide a positive image colored in purple only on the exposed part.
