The invention provides curable waterborne coating compositions comprising an aqueous dispersion (A) comprising an organic binder component (A1) comprising at least 5% by weight of a reactive component (a), based on the total weight of organic binder component (A1), and at least one crosslinking component (B). The reactive component (a) is substantially free of any heteratoms and is a not a crystalline solid at room temperature and comprises from (i) 12 to 72 carbon atoms, and (ii) at least two functional groups.
