PURPOSE: A manufacturing method of a sulfoneamide compound, and a manufacturing method of a colored composition are provided to reduce the generation of foreign substances, and to form the colored composition including a soluble or insoluble component pigment. CONSTITUTION: A manufacturing method of a sulfoneamide compound comprises the following steps: sulfone amidizing a compound including -SO3- or -SO3H; washing the outcome from the previous step with an acidic solution or water; and drying the outcome from the previous step to obtain the sulfoneamide compound. The acidic solution has the pH less than 5.

Method for producing sulfonamide compound and colored composition

PROBLEM TO BE SOLVED: To provide a method for producing a sulfonamide compound that can reduce generation of contaminants, when a coated film is formed by using a sulfonamide compound-containing composition, and to provide a method for producing a coloring composition. SOLUTION: This method for producing the sulfonamide compound includes: a first step of sulfonamidating a compound having at least one group selected from the group consisting of -SO 3 - and -SO 3 H; a second step of washing the reaction product obtained in the first step using at least one selected from the group consisting of an acidic aqueous solution and water of 60°C or higher; and a third step of obtaining the sulfonamide compound by drying the washed product obtained in the second step.
