[0002]

2. Description of the Related Art At present, bleaching agents and bleaching detergents for clothing include:
Sodium percarbonate and sodium perborate are mainly used as bleaching bases. However, since sufficient bleaching performance cannot be obtained with these bases alone, organic peracid precursors such as TAED (tetraacetylethylenediamine), PAG (pentaacetylglucose), and OOBS (sodium octanoyloxybenzenesulfonate) came to be used together. These organic peracid precursors react with hydrogen peroxide compounds such as sodium percarbonate to generate organic peracids with high bleaching effects, effectively removing stains such as food stains and yellowing from clothing. , causing fiber embrittlement,
In particular, when the dye is sprinkled on the fibers of colored patterned articles together with the detergent component during soaking and left to stand, there is a problem that the dye on the fibers is also faded at the same time.

As means for solving these problems, a method using an amino acid described in Japanese Patent Publication No. 57-30188 and a method using an acylated amino acid described in Japanese Patent Publication No. 60-40544 have been proposed. A satisfactory anti-fading effect has not yet been obtained. Also, Japanese Patent Application No. 5
The novel bleach activators described in US-179454, acyloxyanilide derivatives, have been found to be effective in preventing dye fading on textiles.
