Aqueous polymeric dispersions comprising the following constituents:(a) from 40 to 95% by weight of one or more monomers containing an ethylenic unsaturated, the corresponding homopolymer of which has a glass transition temperature (Tg) of less than 0 ° C.,(b) from 4 to 58% by weight of one or more monomers comprising an ethylenic unsaturation, the corresponding homopolymer of which has a glass transition temperature (Tg) of higher than 0° C.(c) from 0.05 to 4% by weight of one or more monomers containing at least two ethylenic unsaturations(d) from 0.2 to 5% by weight of one or more monomers containing an unsaturation of ethylenic type and at least one functional group capable of interacting at low temperature, lower than 100° C., in the crosslinking process during the coalescence phase. |
