摘要： Cationically modified white pigments (W) in particulate form, essentially consisting of a particulate inorganic white pigment (M) of a particle size in the range of 0,1 to 40 μm and an applied water soluble, cationic, crosslinked polymer (PA) containing quaternary ammonium groups in salt form, obtainable by reaction of epichlorohydrin or of epichlorohydrin derivatives or precursors with amines, under conditions leading to at least partial crosslinking, optionally in combination with an anionic optical brightener (B) and where the molar ratio of (B) to (PA) is such that the number of cationic charges of the total polymer (PA) is higher than the number of anionic charges of the total anionic optical brightener (B), are surprisingly useful as cationic white pigments in various fields of technique, especially in papermaking.

摘要： The instant invention relates to a process for the rating of optically brightened paper by visually assessing the paper to ensure that it is white, followed by measurement on a highly accurate single reference spectrophotometer to generate a simple rating, which can then be used to inform the consumer or end user of the whiteness level of the paper. The whiteness level is controlled during production by an audited quality system to ensure each sample of paper is identical in rating.
