摘要:
Novel flame retarding compounds that comprise at least one sterically hindered nitroxyl, hydroxylamine or hydrocarbyloxyamine moiety and at least one conventional organohalogen or organophosphorus flame retardant moiety, represented by where HA is independently of each other a sterically hindered nitroxyl, sterically hindered hydroxylamine or sterically hindered hydrocarbyloxyamine moiety, L is independently of each other a direct bond or chemical linking group, FRM is independently of each other an organohalogen or an organophosphorus flame reatardant moiety, and x, y and z are each independently greater than or equal to 1, are especially effective towards providing flame retardancy to organic polymer substrates.

摘要:
The present invention relates to a method for preparing (pearlescent) pigments, comprising the steps of: (1) coating of a sheet silicate with a desired metal oxide, wherein coated flakes are obtained, (2) delamination of the coated flakes obtained in step (1), wherein exfoliated coated flakes and exfoliated non-coated flakes are obtained, (3) separation of the exfoliated coated flakes from the exfoliated non-coated flakes, (4) coating the exfoliated coated flakes obtained in step (3) with metals, metal oxides, metal sulfides, metal nitrides or mixtures thereof, wherein a (pearlescent) pigment is obtained; to (pearlescent) pigments, obtainable by the process and to the use of the (pearlescent) pigments in paints, ink-jet printing, for dyeing textiles, for pigmenting coatings, printing inks, plastics, cosmetics, glazes for ceramics and glass.
摘要:
Novel fluorescent polyhedral oligomeric silsesquioxane (POSS) colorants are provided. The colorants are strongly fluorescing and long lasting with excellent light stability. The novel colorants can be prepared from chromophores found in common pigments and provide a simple way to convert an insoluble pigment into a soluble fluorescent colorant.
