    • The invention provides a novel bleaching composition comprising:(a) an oxidatively stable bleach activator having the structure ##STR1## wherein Y.sub.1, Y.sub.3 and Y.sub.4 each represents a bridging group, i.e., zero, one, two or three carbon containing nodes for substitution while Y.sub.2 is a bridging group of at least one carbon containing node for substitution, each said node containing a C(R), C(R.sub.1)(R.sub.2), or a C(R).sub.2 unit and each R substituent is the same or different from the remaining R substituent and is selected from the group consisting of H, alkyl, cycloalkyl, cycloalkenyl, alkenyl, aryl, alkynyl, alkylaryl, halogen, alkoxy, or phenoxy, CH.sub.2 CF.sub.3, CF.sub.1 and combinations thereof, or form a substituted or unsubstituted benzene ring of which two carbon atoms in the ring form notes in the Y unit, or together with a paired R substituent bound to the same carbon atom form a cycloalkyl or cyloalkenyl ring, which may include an atom other than carbon, e.g., cyclopentyl or cyclohexyl; M is a transition metal with oxidation states of I, II, III, IV, V or VI, or selected IV from Groups VIA, VIIA, VIII, and IB; Q is any counterion which would balance the charge of the compound on a stoichiometric basis; L is any labile ligand; and,(b) an effective amount of a source of peroxy compound.
    • 本发明提供了一种新颖的漂白组合物,其包含:(a)具有结构的氧化稳定的漂白活化剂,其中Y 1,Y 3和Y 4各自表示桥连基团,即用于取代的0,1,2或3个含碳的结点,而Y2是 每个所述节点含有C(R),C(R 1)(R 2)或C(R)2单元,并且每个R取代基与剩余的碳原子的相同或不同) R选自H,烷基,环烷基,环烯基,烯基,芳基,炔基,烷基芳基,卤素,烷氧基或苯氧基,CH 2 CF 3,CF 1及其组合,或形成其取代或未取代的苯环 环中的两个碳原子在Y单元中形成音符,或与与相同碳原子结合的成对的R取代基一起形成环烷基或环烯基环,其可以包括除碳以外的原子,例如环戊基或环己基; M是氧化态为I,II,III,IV,V或VI的过渡金属,或VIA,VIIA,VIII和IB族选自IV; Q是以化学计量为基础平衡化合物的电荷的任何抗衡离子; L是任何不稳定的配体; 和(b)有效量的过氧化合物源。
