The present invention relates to the use of a composition comprising specific a-amino-ketones, HO, a HOprecursor or a peracid and optionally an activator as a bleaching mixture for textile materials or dishes either manually or in an automatic washing machine or dish washer. Further aspects of the invention are the composition comprising specific a-aminoketones and HO, a HOprecursor or a peracid and a process for bleaching of stains or of soiling on textile materials or dishes in the context of a washing process either manually or in an automatic washing machine or dish washer. Also aspects of the invention are detergent formulations comprising such a composition and novel compounds.

Metal free bleaching composition

The invention pertains to high-molecular photoinitiator compounds comprising a photoactive moiety Q and an amine functionality, preferably a tertiary amino group, where the photoactive moiety Q is a benzoyl photoactive moiety.

Macrophotoinitiators

Photoinitiator compounds comprising both a photoactive moiety and an amine functionality, bonded to a polyhedral oligomeric silsesquioxane, which photoinitiator is represented by formula (1) or (1') wherein n is 2m; m is an integer of 2 to 30; the sum of n&#x2032;+a is an integer 4-60; n&#x2032; is an even-numbered integer; a is an even- or uneven-numbered integer; and for example different A C-Calkyl, or a photoactive moiety Q1, or a group of formula (2); E for example is a direct bond, L is linear or branched C-Calkylene, preferably propylene; Rand Rfor example are a photoactive moiety Q, or Calkyl; Q is for example a group of formula (4); Zis for example C-Calkylene which is unsubstituted or substituted by one or more OR; and R, R, Rand Rfor example are hydrogen; are especially suitable as low-migrating photoinitiators. 

Silsesquioxane photoinitiators

The invention relates to novel benzotriazole UV-absorbers having a long wavelength shifted absorption spectrum with significant absorbance up to 410-420 nm. Further aspects of the invention are a process for their preparation, a UV stabilized composition containing the new UV-absorbers and the use of the new compounds as UV-light stabilizers for organic materials. 

Long wavelength shifted benzotriazole UV-absorbers and their use

The present invention relates to the use of metal complex compounds which have terpyridine ligands and contain at least one quaternized nitrogen atom as oxidation catalysts. The present invention relates also to formulations comprising such metal complex compounds, to novel metal complex compounds and to novel ligands.
