| abstract | Dyes according to the formula: <CHEM> R1 and R2 are each independently substituted or unsubstituted alkyl or substituted or unsubstituted aryl, or together represent the atoms necessary to complete a substituted or unsubstituted 5- or 6-membered ring, R3 is substituted or unsubstituted alkyl or aryl, R4 and R5 each independently represents H, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, CO2H, or NHSO2R6, with the proviso that at least one of R4, R5, or a substituent on an aryl R3, on an aryl R1 or R2, or on an aryl ring formed by R1 and R2 is CO2H or NHSO2R6, R6 is substituted or unsubstituted alkyl or substituted or unsubstituted aryl, R7 is substituted or unsubstituted alkyl, or together with R8 forms a double bond, R8 is H or together with R7 forms a double bond, and n is 1 or 2. e |
