ABSTRACT:
Tear resistance and flexibility of resin-treated textiles are improved while retaining good low temperature properties by using as the resin an acrylic emulsion polymer wherein the latex particles have a core-shell structure. The monomers forming the core are selected to provide a Tg in the core of -20.degree. C. or lower and the monomer composition forming the shell is selected to provide a Tg in the shell of about 60.degree. C. to about -10.degree. C. The core monomer composition contains 4-10 wt. % of a latent crosslinker together with 0-0.03 wt. % of an active crosslinker or a graftlinker, and the shell monomer composition contains 2-10 wt. % of a latent crosslinker.
