摘要： PROBLEM TO BE SOLVED: To provide a blue coloring agent by gold nano fine particles of the quality same as that of a gold hydrosol (gold colloid) widely used as a color material of red to purple.
SOLUTION: Spiculisporic acid as a biosurfactant (a surfactant produced by an organism) with a tribasic acid type structure derived from an organism, safe and having biodegradability and various alkali salts of the lactone ring opened body thereof are used as a reducing agent of Au
3+ of a chloroauric acid aqueous solution in the coexistence of monovalent inorganic salts. After reduction reaction, the unreacted biosurfactant and the oxide thereof are adsorbed on gold nano fine particles in the produced gold hydrosol and gold hydrogel so as to stabilize a water dispersion system of the gold nano fine particles. Alternatively, the blue coloring agent is made of a water dispersion system of gold nanofine particles prepared by adding monovalent inorganic salts to a red system gold hydrosol obtained by reducing chloroauric acid by the biosurfactant.

摘要： PROBLEM TO BE SOLVED: To provide materials for various uses, such as a thick and stable nanocolloidal gold liquid, a fine gold particle and a gold paste obtained by reducing a thick aqueous solution of chloroauric acid at a reaction temperature in a wide range from low temperature to ordinary temperature without requiring operation of concentration and addition of protective colloid agent for preparation of thick gold colloid.
SOLUTION: An alkali salt of spiculisporic acid (a safety biosurfactant of biological origin, having a tribasic acid type structure) and an alkali salt of a lactone ring-opened substance thereof are used both as a reducing agent and a colloid protecting and stabilizing agent. These are added to an aqueous solution of chloroauric acid, and the resulting mixture is mixed by shaking at a temperature ranging from ordinary temperature to high temperature (5 to 80°C) and is then allowed to stand still. The aqueous solution of chloroauric acid having high to low concentration (0.1 mmol/l to 2.43 mol/l) is reduced to form gold nanoparticles, and the number of nucleations of gold as a simple substance and the uniting thereof are controlled, and the resulting gold colloid is provided with a high dispersion stabilizing action.
