Provided is a binder composition and its use in aqueous based paints and coatings and other applications. The binder composition comprises: (a) a copolymer formed from one or more esters or amides of acrylic acid or methacrylic acid, or their mix -tures, together with a monomer unit of formula I, wherein R, R1 R2, R3, R4, and X are as defmed above; and (b) water, wherein the binder composition is an aqueous emulsion. La présente invention concerne un composition de liant et son utilisation dans des peintures et revêtements aqueux et d'autres applications. La composition de liant comporte : (a) un copolymère formé à partir d'un ou de plusieurs ester(s) ou amide(s) de l'acide acrylique ou de l'acide méthacrylique, ou leurs mélanges, conjointement avec une unité monomère de formule I, dans laquelle R, R1 R2, R3, R4, et X sont tels que définis dans la description ; et (b) de l'eau, la composition de liant étant une émulsion aqueuse.
