ABSTRACT:
Disclosed is a radiation crosslinkable water-dispersible adhesive composition that is useful in forming paper and plastic articles and other products that can be recycled through a process which includes washing or repulping in aqueous media. The cross-linkable water-dispersible adhesive composition is preferably used as a hot melt adhesive. The cross-linkable water-dispersible adhesive composition is a low molecular weight, branched copolyester containing a sulfomonomer and unsaturated moieties. The radiation crosslinked adhesive composition has more cohesive strength and viscosity than its corresponding uncross-linked adhesive, yet is still water-dispersible during product recycling.
