2. Description of the Related Art Chlorine-based bleaching agents, which have been widely used as liquid bleaching agents, are inexpensive and have a strong bleaching power, but they cannot be used for colored patterned clothing because they discolor or discolor the object to be treated. However, in recent years, there has been a social problem that chlorine gas is generated due to the accidental mixing with an acidic cleaning agent, causing a fatal accident. On the other hand, the oxygen-based bleaching agent is excellent in that it can be used in a wide range of clothes and there is no problem of chlorine gas generation. However, most of the commercially available oxygen-based bleaching agents are sodium percarbonate and sodium perborate, and these have the problem that the bleaching effect is low at low temperatures, although the discoloration and fading of the color pattern is small. Therefore, in order to solve the above-mentioned problems, various methods have been proposed in which various activators are added to hydrogen peroxide or hydrogen peroxide adduct to effect effective bleaching at low temperature. For example, a method in which an N-acyl compound is used as an activator and reacted with hydrogen peroxide in a bleaching bath to generate peracetic acid to enhance the bleaching effect (Japanese Patent Publication No. 38-
No. 10165) is known. However, these bleaching effects are not sufficient, and the object to be treated may be discolored and discolored by the bleaching agent. For this reason, the oxygen bleaching agent is still more satisfactory than the chlorine bleaching agent. The actual situation is that it has not achieved the effect.
