Claims

1. The compound having the formula:

where X represents O or NH; M represents hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; each R ₁ independently represents an amino acid residue from which a hydrogen atom on an amino group has been removed; n is 1 or 2; and each R ₂ independently represents hydrogen, C ₁ -C ₃ alkyl, halogen, cyano, COOR, where R represents hydrogen or C ₁ -C ₃ alkyl, CONH-R, where R represents the value indicated above, SO ₂ NH-R where R has the meaning indicated above, NH-COR, where R has the meaning indicated above, SO ₃ M, where M has the meaning indicated above; or, if n is 1, then R ₂ may also be CO-R ₃ , where R ₃ is C ₁ -C ₃ alkyl or phenyl;
provided that such compounds are excluded in which:
a) X is NH, n is 1, and R ₂ is SO ₃ M, where M is as defined above; or
b) X is NH, n is 2, and one of R ₂ is SO ₃ M, where M is as defined above and the other R ₂ is hydrogen, methyl or halogen, or
c) X is NH, n is 1, R ₁ is glycine, and R ₂ is H or CO ₂ H; or
d) X is NH, n is 2, each of R ₂ is SO ₃ M, where M is as defined above, and SO ₃ M groups are in the 2,5-positions of the phenyl ring, and R ₁ is D, L- alanine, L-valine, L-leucine, L-isoleucine, L-threonine, L-aspartic acid, L-glutamic acid, L-phenylalanine, L-proline, D, L-methionine or glycine.

2. The compound according to claim 1, where all amino acid residues R ₁ are the same and each of them has the formula —NH — CH (CO ₂ H) —R ₃ , where R ₃ represents hydrogen or a group having the formula —CHR ₄ R ₅ in which R ₄ and R ₅ independently represents hydrogen or C ₁ -C ₄ alkyl optionally substituted with one or two substituents selected from hydroxy, thio, methylthio, amino, carboxy, sulfo, phenyl, 4-hydroxyphenyl, 3,5- diiod-4-hydroxyphenyl, β-indolyl, β-imidazolyl and NH = C (NH ₂ ) NH-.

3. A method of fluorescent whitening of a substrate, comprising contacting the substrate with a compound of formula (1A):

where X represents O or NH; M represents hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; each R ₁ independently represents an amino acid residue from which a hydrogen atom on an amino group has been removed; n is 1 or 2; and each R ′ ₂ independently represents hydrogen, C ₁ -C ₃ alkyl, halogen, cyano, COOR, where R represents hydrogen or C ₁ -C ₃ alkyl, CONH-R, where R has the meaning indicated above, SO ₂ NH- R, where R has the meaning indicated above, NH-COR, where R has the meaning indicated above, or SO ₃ M, where M has the meaning indicated above;
with the proviso that compounds in which X is NH, n is 2, and one of R ₂ is SO ₃ M, where M is as defined above and the other R ₂ is hydrogen, methyl or halogen, are excluded.

4. The method according to claim 3, fluorescent whitening of the surface of the paper, comprising contacting the surface of the paper with a composition for coating, including a white pigment; a dispersion of a binding agent, optionally a water-soluble co-binder; and a sufficient amount of the fluorescent whitening agent of the present invention having the formula 1A, so that the treated paper contains 0.01 to 1% by weight of a fluorescent whitening agent having the formula 1A based on the weight of the white pigment.

5. The method according to claim 3 of the fluorescent whitening of the paper surface, comprising contacting the paper in the size press with an aqueous solution containing an adhesive agent, optionally an inorganic or organic pigment, and 0.1 to 20 g / l of a fluorescent whitening agent having the formula 1A.

6. The method according to claim 3, fluorescent whitening of the surface of the paper, comprising adding a fluorescent whitening agent having the formula (1A) to the aqueous paper pulp in a wet state.

7. A method of increasing the C3C value of a textile fiber material, comprising treating a textile fiber material of 0.05-3.0% by weight of one or more compounds of formula 1A as defined in claim 3, based on the weight of the textile fiber material.

8. The method according to claim 7, where in addition to the compounds of formula 1A, a small amount of one or more adjuvants can also be used.

9. The method of claim 8, wherein said adjuvants are emulsifiers, perfumes, whitening agents, enzymes, dyes, opacifiers, optical whitening agents, bactericides, nonionic surfactants, tissue care ingredients, anti-gel agents, or inhibitors corrosion.

10. A method for increasing the C3C value of a textile material material according to claim 7, comprising washing the material with a detergent containing at least one compound of formula 1A to give the textile material so washed that has excellent sun-protection properties.

11. The method of claim 10, wherein the detergent composition used comprises:
i) 5 to 90% of an anionic surfactant and / or a nonionic surfactant;
ii) 5 to 70% of a shaping agent;
iii) 0-30% peroxide;
