摘要： The instant invention relates to stilbene optical brightening agents which combine a high solubility in water while providing superior fluorescent whitening effects when applied to the surface of paper in either the size-press or in a pigmented coating composition and which show a reduced anionic charge. The instant optical brighteners may also be used for finishing of textiles.

摘要： The instant invention relates to concentrated aqueous solutions of hexasulphonated stilbene optical brighteners which are storage-stable in the absence of solubilizing agents like urea. By removal of salts resulting from the preparation of the optical brightener one can obtain a concentration of up to 0.350 mol/kg without losing storage stability. The reduced water content enables coating compositions which require less drying energy and which show less water and binder migration into the paper.
