Abstract

The invention relates to an aqueous polyolefin dispersion comprising a. from 50 to 100 wt. % of an aqueous dispersion A comprising the following ingredients: i. from 60.0 to 98.9 wt. % of A1, a copolymer of polyethylene and (meth)acrylic acid [E(M)AA] or a mixture of different copolymers of polyethylene and (meth)acrylic acid, ii. from 1.0 to 39.0 wt. % of A2, another polymer or a mixture of other polymers, not being a copolymer of polyethylene and (meth)acrylic acid, selected from the group consisting of copolymers of ethylene and vinyl acetate (EVA) and copolymers of ethylene and vinyl acetate (EVA) modified with maleic anhydride, iii. from 0.1-10.0 wt. % of a silicate component A3 (wt. % refers to the relevant SiO2 content) and iv. from 0-20 wt. % of additive not being A1, A2 or A3,b. from 0 to 50 wt. % of a compound B, where compound B is a material dispersable or soluble in water and different from any of the ingredients of dispersion A wherein—the wt. % of A and B is based on the solid content of the whole aqueous polyolefin dispersion, —the wt % of the ingredients of dispersion A is based on the solid content of dispersion A, the sum of the wt. % of ingredients i to iv) of dispersion A is 100%.
