The present invention provides a crosslinkable polymer composition in the form
of its aqueous polymer dispersion or polymer powder, including A) a copolymer having
a glass transition temperature Tg or a melting temperature of 30
C. and containing units derived from one or more comonomers selected from the group
consisting of vinyl esters of branched or unbranched alkylcarboxylic acids of 1
to 18 carbon atoms, acrylic esters or methacrylic esters of branched or unbranched
alcohols of 1 to 15 carbon atoms, dienes, olefins, vinyl aromatics and vinyl halides
and from 0.1 to 50% by weight, based on the total weight of the comonomers, of
one or more ethylenically unsaturated carboxyl-containing comonomers, and B) a
copolymer containing units derived from one or more comonomers selected from the
group consisting of vinyl esters of branched or unbranched alkylcarboxylic acids
of 1 to 18 carbon atoms, acrylic esters or methacrylic esters of branched or unbranched
alcohols of 1 to 15 carbon atoms, dienes, olefins, vinyl aromatics and vinyl halides
and from 0.1 to 50% by weight, based on the total weight of the comonomers, of
one or more ethylenically unsaturated comonomers having functional groups capable
of entering a covalent bond with the carboxyl groups of said copolymer A).
