Substituted sulfonated coumarins are expressed in the general formula (I), where: R1 is H, OH, or a substituted or unsubstituted, straight or branched C1-C6 alkyl radical, or —COR4, or —COOR4, or —CONHR4, R2 is H or a halogen, in particular fluorine, or a substituted or unsubstituted, straight or branched C1-C6 alkyl radical, or —COR4, or —COOR4, or —CONHR4, R1 and R2 being capable of together forming a ring, such as a substituted or unsubstituted aryl or furane, R3 is H or a halogen, in particular fluorine, or a substituted or unsubstituted, straight or branched C1-C6 alkyl radical, or —COR4, or —COOR4, or —CONHR4, where R4 is H, or a substituted or unsubstituted, straight or branched C1-C6 alkyl radical, or a substituted or unsubstituted aryl, and M is Na or K.
