A copolymer emulsion latex having a solids content of 20% to 70% by weight, preferably 40% to 60%, in which vinyl C1 to C13 alkanoate forms at least about 40% by weight of the monomer charge. Polymerisation is performed in the presence of an effective amount of stabilising system comprising at least one surfactant capable of providing sharp nucleation in the polymerisation process and at least one surfactant including a C14 to C20 alkylene moiety.
