This invention relates to methods and compositions for materials having a non-leaching or slow-realising coating that has antimicrobial properties. The coating is applied to substrates such as silicates, iron oxides, titanium dioxide, pigments, powders and other substrates. Covalent bonds or ionic bonds are formed between the substrate and the polymer molecules that form the coating.

The invention relates to a method for depositing a polymer onto a surface, by applying an aqueous composition, preferably an aqueous composition, onto said surface. The invention also relates to a method for making the composition. The composition comprise a block copolymer, comprising at least two blocks A and B, wherein block A is a polyionic block and block B is a neutral block.
The present invention relates to novel compounds that are particularly useful for the alignment, especially photoalignment, of slave material, especially liquid crystals for optical or electro-optical applications, such as security applications, liquid crystal devices or optical or electro-optical films.
