    • The invention provides a hair colouring composition comprising one or more developers selected from amino aromatic systems capable of being oxidised and thereafter undergoing at least two electrophilic attack reactions, and one or more couplers selected from (a) 1,3-diketones of the formula (I): in which X and Y are non-leaving substituents and Z is an active leaving group, such that in the presence of an oxidising agent the or each developer reacts with the or each coupler substantially only at the position having the active leaving group Z and (b) compounds of the formula (II): in which R1, R2 and R3 are, independently, cycloalkyl, alkenyl, cycloalkenyl, aryl, alkaryl, aralkyl, -R'NHCOR, -CONHR, -R'CONHR, -R'OH, -R'SO2R, -R'SO2NHR, -R'OR or -COR, in any of which R is H, alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, alkaryl or aralkyl and R' is alkylene, alkenylene, cycloalkylene, cycloalkenylene, arylene, alkarylene or aralkyrene, or substituted versions of any of these.
    • 本发明提供一种头发着色组合物,其包含一种或多种显影剂,所述显影剂选自能够被氧化的氨基芳族体系,然后经历至少两次亲电子攻击反应,以及一种或多种选自(a)1,3-二酮 I):其中X和Y是非离去取代基,Z是活性离去基团,使得在存在氧化剂的情况下,每个显影剂基本上仅在具有活性离去基团的位置处与该或每个成色剂反应 Z和(b)式(II)的化合物:其中R1,R2和R3独立地是环烷基,烯基,环烯基,芳基,烷芳基,芳烷基,-R'NHCOR,-CONHR,-R'CONHR, - R'OH,-R'SO2R,-R'SO2NHR,-R'OR或-COR,其中R是H,烷基,环烷基,烯基,环烯基,芳基,烷芳基或芳烷基,R'是亚烷基,亚烯基 ,亚环烷基,亚环烯基,亚芳基,亚烷芳基或芳烯基,或这些中的任何一种的取代形式。
