The present invention relates to a laundry shading process with specific blue or violet bisazo-dyes alone or in combination with a photocatalyst. Further aspects of the invention are a composition comprising at least one photocatalyst and at least one of the specific bisazo-dyes. The composition is particularly useful for shading textiles during laundry. Further aspects of the invention are a detergent composition, a fabric softener composition containing these dyes or mixtures of these dyes and photocatalysts and novel blue or violet bisazo-dyes.

Dyes and blends for shading during laundry

The present invention relates to new compounds, which are molecular combinations of a phthalocyanine and a mono-azo dyestuff linked via specific linking groups and to a process for their preparation. Further aspects are shading compositions using these compounds.

Shading process

The present invention relates to new compositions comprising compounds, which are molecular combinations of a phthalocyanine and a mono-azo dyestuff linked via specific linking groups. Further aspects are an improved shading process for textile materials and also use of these shading compositions for shading textiles.

Shading compositions

A process for improving the sun protection factor (SPF) of cellulosic fibre materials and blends thereof, which comprises contacting said materials with at least one compound of the formula (1) in which M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; Rand R' independently of each other are hydrogen, hydroxy, optionally substituted alkyl, 4-morpholinyl, &#x2014;NH&#x2014;R, &#x2014;N(R)or &#x2014;O&#x2014;Rwherein Ris optionally substituted alkyl or optionally substituted aryl, Ris a group of formula (2) wherein X is &#x2014;O&#x2014; or &#x2014;NH&#x2014; and Ris C-C-alkyl which carries at least one hydrophilic substituent and R&#x2032; has the meaning of Ror R.

A method for the fluorescent whitening of cotton in a discontinuous process comprising contacting the cotton, I an aqueous bath having a pH value of 6 or less, with one or more compounds of the Formula (I) wherein Rrepresents an &#x2014;SOR, &#x2014;SOR, COM, &#x2014;COR, &#x2014;CONRR, &#x2014;CN or &#x2014;NOsubstituent, Ris &#x2014;NH, &#x2014;NH(C-Calkyl), &#x2014;N(C-Calkyl), &#x2014;NH(C-Chydroxyalkyl), &#x2014;N(C-Chydroxyalkyl), &#x2014;NH(C-Calkoxy)(C-Calkyl), &#x2014;N[(C-Calkoxy)(C-Calkyl)], NHC&#x2014;Calkylsulphonic acid, morpholineo, piperidino pyrrolidino, an amino acid or amino acid amide residue from which a hydrogen atom on the amino group has been removed, &#x2014;OC-Calkyl or &#x2014;OC-Chydroxyalkyl, Rand Reach, independently, represent hydrogen, C-Calkyl, C-Chydroxyalkyl or C-CalkoxyC-Calkyl and M is H, Na, Li, K, Ca, Mg, ammonium, or ammonium that is mono-, di-, tri- or tetrasubsituted by C-Calkyl, C-Chydroxyalkyl or a mixture thereof, some of which are new

Method for the fluorescent whitening of cotton

The present invention relates to a mixture of fluorescent whitening agents comprising 20 to 70% by weight of a compound of formula (1), 30 to 80% of a compound of formula (2) and 0.1 to 10% of a compound of formula (3), compositions containing the mixture and the user of the compositions for whitening synthetic fibers, in particular, polyester.

Mixtures of fluorescent whitening agents

The present invention relates to a mixture of fluorescent whitening agents comprising 20 to 70% by weight of a compound of formula (1), 30 to 80% of a compound of formula (2) and 0.5 to 5% of a compound of formula (3), compositions containing the mixture and the use of the compositions for whitening synthetic fibers, in particular polyester.
