Inorganic Brighteners

Titanium pigments absorb in the near visible UV-range. Their efficiency is less in comparison to anatase pigments that are absorbing ca. 40% of the UV light in the range of wavelength of 380 nm. [Pg.52]

Inorganic salts (polyphosphate, silicates) Optical brighteners... [Pg.136]

Optical brighteners are also used to enhance the whiteness of various inorganic and organic substrates, such as tripolyphosphates, carbonates, and photographic papers [152-154],... [Pg.615]

If the solubility of inorganic salts in the chosen medium is low, complexing additives are used [174,185] which apparently also exert a brightening effect. [Pg.78]

Starch anthranilates were proposed as optical brighteners. They improve the retention of inorganic fillers and fiber fines in paper processing.2535,2536... [Pg.280]

Helwig also showed that the mars pigments were variously extended with gypsum, barytes and aluminium oxides and occasionally brightened with other inorganic and organic pigments. [Pg.254]
