Definitions
- the invention relates to the use of special brighteners for the production of coating slips, coating slips per se and their use for the production lightened papers.
- Optical brighteners are mainly used for whitening paper, textiles or used as an additive to detergents.
- the white tint of uncoated paper or coating base papers can by mass application and / or surface application of optical brighteners, which are usually available in dissolved form.
- optical brighteners When producing coated papers, the addition of optical brighteners is necessary Brush color usual, so that the optical brightener when finished coated Paper is also located in the pigment layer applied to the paper. Painted Papers are particularly suitable for making high-quality prints. Besides good ones Printability properties are therefore mainly based on optical quality Properties such as gloss and whiteness are assessed. There is a continuing trend towards coated papers with high degrees of whiteness and therefore the desire for as much as possible effective optical brighteners as coating color components.
- the effect of saturation is also called greening.
- the greening limit i.e. the point at which increasing amounts of brightener are used practically no longer increase the degree of whiteness, e.g. from the a * b * diagram are derived, where a * and b * are the color coordinates in the CIELab system are.
- the hexasulfoflavonate brightener shown in formula (I) is also suitable especially for the production of coated, bright white papers.
- the exact amounts used, in which the greening occurs with tetra- or hexasulfoflavonate brighteners, depend on the composition of the respective coating color, including of their Carrier salary from.
