Description
【0001】
【発明の属する技術分野】
本発明は、過酸化水素又は水溶液中で過酸化水素を発生する過酸化物、有機過酸のような有機ペルオキシド化合物を使用する漂白剤を活性化させるための漂白活性化剤、特に低温においても優れた活性化効果を有する、漂白活性化剤及びそれを含有する漂白剤に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
洗濯用に過酸化水素等のペルオキシ漂白剤を利用することは公知の技術である。このペルオキシ漂白剤は高温で使用され、紅茶、コーヒー、ワイン、果物の漂白に有効である。しかし、ペルオキシ漂白剤の効果は60℃以下では極端に低下する。そのため、遷移金属錯体を漂白活性化触媒として用いることが検討されているが、これまでの遷移金属錯体では十分な漂白活性化効果が得られず、さらには染料の脱色を引き起こし、繊維を損傷するなどの問題があった。
【0003】
したがって本発明の課題は、十分な漂白活性化効果を有し、繊維損傷や染料脱色を引き起こさない漂白活性化剤及び漂白剤を提供することにある。
【0004】
【課題を解決するための手段】
