    • The present invention provides, as a first aspect, an asymmetric compound having the formula: in which M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; Xa and Xb are the same or different and each is NH2; NH(C1-C4alkyl); NH(C2-C4alkoxyalkyl); N(C1-C4alkyl)2; N(CH2CH2OH)2; a group NH—Z—NR1R2 in which Z is C2-C14alkylene or optionally substituted arylene, and R1 and R2 are the same or different and each is C1-C12alkyl or R1 and R2, together with the nitrogen atom to which they are each attached, form a morpholino, piperidino or piperazino ring; an aminoacid residue; C1-C4alkoxy; hydroxy-substituted-C2-C4alkoxy; and Ya and Yb are the same or different and each is a substituted amino group having both UVA and UVB-absorbing properties having the formula: in which R3 is CN; SO2R5 in which R5 is, C1-C12alkyl, C1-C12alkoxy, NH2, NH(C1-C4alkyl), N(C1-C4alkyl)2, N(CH2CH2OH)2, C1-C4alkoxy or hydroxy-substituted-C2-C4alkoxy; COR5 in which R5 has its previous significance; COOM in which M has its previous significance or NHCOR5 in which R5 has its previous significance and in which R4 has the same significance as R3 or is H, OH, C1-C4alkyl or C1-C4alkoxy and one of Xa and Xb can be identical to one of Ya and Yb, provided that one of Xa and Xb is different from the other and/or one of Ya and Yb is different from the other. The present invention also relates to a method of improving the sun protection factor (SPF) of textile fibre material, especially cotton, polyamide and wool, comprising treating them with the new compounds.
    • 作为第一方面,本发明提供具有下式的不对称化合物:其中M是氢,碱金属原子,铵或由胺形成的阳离子; Xa和Xb相同或不同,各自为NH 2; NH(C 1 -C 4烷基); NH(C 2 -C 4烷氧基烷基); N(C 1 -C 4烷基)2; N(CH 2 CH 2 OH)2; 其中Z为C 2 -C 14亚烷基或任选取代的亚芳基的基团NH-Z-NR 1 R 2,并且R 1和R 2相同或不同,并且各自为C 1 -C 12烷基或R 1和R 2以及它们各自连接的氮原子 形成吗啉代,哌啶子基或哌嗪基环; 氨基酸残基; C1-C4烷氧基; 羟基取代的C 2 -C 4烷氧基; Ya和Yb相同或不同,并且各自为具有下式的UVA和UVB吸收性质的取代氨基:其中R3为CN; 其中R 5为C 1 -C 12烷基,C 1 -C 12烷氧基,NH 2,NH(C 1 -C 4烷基),N(C 1 -C 4烷基)2,N(CH 2 CH 2 OH)2,C 1 -C 4烷氧基或羟基取代的C 2 -C 4烷氧基的SO 2 R 5; COR5其中R5具有以前的意义; 其中M具有其先前意义的COOM或其中R5具有其先前意义的NHCOR5,并且其中R 4与R 3具有相同的含义或为H,OH,C 1 -C 4烷基或C 1 -C 4烷氧基,X a和X b中的一个可以相同 Ya和Yb中的一个,其中Xa和Xb中的一个与另一个不同,和/或Ya和Yb中的一个与另一个不同。本发明还涉及一种改善防晒因子(SPF)的方法 纺织纤维材料,特别是棉花,聚酰胺和羊毛,包括用新化合物处理它们。
