20090230345 | Aqueous Polymer Dispersion Useful for Preparing Base-Coat Composition for Embossed Leather - The invention relates to an aqueous polymeric dispersion comprising polymeric particles bearing silane and carboxylic groups, the said carboxylic groups being possible to be either in the form of acid or of its salt with monovalent cation, the said polymer particles being crosslinked by the presence of at least one multivalent metal compound selected from: oxides, hydroxides or its salts or complexes, with the Tg of the said polymer being not higher than | 09-17-2009 |
20100288962 | FLUOROPOLYMER - Various fluoropolymers have been proposed for imparting oil and water repellency to leather. Commonly, these fluoropolymers are amphiphilic; i.e., they are made from at least one monomer which is hydrophobic and at least one monomer which is hydrophilic. The present invention identifies and remedies disadvantages associated with the ability of amphiphilic fluoropolymers to impart oil and water repellency to leather. Contrary to conventional thinking, it has now been discovered that the incorporation of hydrophilic groups in a fluoropolymer undesirably reduces its ability to impart water resistance to leather. Correspondingly, it has also been discovered that a fluoropolymer incorporating fewer or no hydrophilic groups imparts superior oil and water repellency to leather when compared to fluoropolymers incorporating more hydrophilic groups. Therefore, this invention provides fluoropolymers which incorporate reduced levels of hydrophilic groups. | 11-18-2010 |
