Abstract:
Aqueous polymer composition suitable for coating which comprises the following components dispersed in water:(1) a combination of an acrylic polymer(s) A and an acrylic polymer(s) B where polymer(s) A has a Tg of not more than 30Â° C. and polymer(s) B has a Tg of at least 35Â° C., which is at least 25Â° higher than the Tg of polymer(s) A, and wherein one or both of polymers A and B bear crosslinker functional groups capable of imparting ambient-temperature crosslinkability to component (1) in a coating formed from the composition via the formation of non-radically-formed covalent bonds; and (2) a self-dispersible, ionically stabilised polymer having olefinically unsaturated bond functionality capable of imparting radiation-curability thereto in a coating formed from the composition.
