Abstract (en)
[origin: WO2009123637A1] A paper coating or binding formulation comprises an aqueous polymer dispersion comprising a copolymer obtained by polymerization of an unsaturated monomer and a carbohydrate derived compound and a tetrasulfonate-based fluorescent whitening agent. The carbohydrate derived compound can be selected from the group consisting of dextrins, maltodextrins, and mixtures thereof. Methods of preparing a paper coating or binding formulation and improving the whitening properties of paper are also provided. Furthermore, paper including a copolymer obtained by polymerization of an unsaturated monomer and a carbohydrate derived compound and a tetrasulfonate-based fluorescent whitening agent is also disclosed.
