PURPOSE: A stripper composition is provided to maintain superior stripping intensity in addition to prevent the precipitation of an inorganic alkali compound. CONSTITUTION: A stripper composition includes an inorganic alkali compound, water, and a C3-7 protic solvent with a hydroxyl group. The content ratio of the protic solvent and the inorganic alkali compound is 1 : 0.5-9 based on weight. The content ratio of water and the inorganic alkali compound is 1 : 0.3-0.8 based on weight. The inorganic alkali compound is sodium hydroxide or potassium hydroxide. The protic solvent is one or more selected from a group consisting of glycols and glycerols. |
