Abstract (en)
[origin: WO9311194A1] Improved gloss pigments are produced by coating platelike substrates and are characterised in that an aqueous suspension composed of a metallic salt and of metal oxide and/or dyestuff particles is hydrolytically precipitated on the platelike substrat as a metal oxide-and/or dyestuff particles-containing metal hydroxide layer.
Abstract (fr)
Des pigments à éclat amélioré sont obtenus par revêtement de substrats en paillettes. Ces pigments se caractérisent par le fait que l'on précipite par hydrolyse sur le substrat en paillettes une suspension aqueuse constituée d'un sel métallique, ainsi que de particules d'un oxyde métallique et/ou d'un colorant, de manière à former une couche en hydroxyde métallique contenant des particules d'oxyde métallique et/ou de colorant.
