Claim 1
Independent Claim
227 words
A water-soluble compound of the formula (1), (2), or (3) ##STR2## wherein A 1 , A 2 , A 3 , A 4 , A 5 and A 6 are the same or different, and each represents alkyl or alkoxyalkyl containing up to 6 carbon atoms, provided that in formula (1), one of A 1 and A 4 is optionally --(CH 2 ) 1-4 CO 2 - or --(CH 2 ) 1-4 SO 3 - ; in formula (2), two of A 1 , A 2 , A 4 , and A 5 are selected from the group consisting of --(CH 2 ) 1-4 CO 2 - and --(CH 2 ) 1-4 SO 3 - ; and in formula (3) three or four of A 1 , A 2 , A 3 , A 4 , A 5 , and A 6 are selected from the group consisting of --(CH 2 ) 1-4 CO 2 - and --(CH 2 ) 1-4 SO 3 - ; X -1 is an anion; M +1 is a cation; a is 1 to 4; b is 1 to 4; c is 5 to 8; x is 1 or 2 and is selected so that the compound of formula (1) is ionically neutral; and m is 1 or 2 and is selected so that the compound of formula (3) is ionically neutral.
