Abstract
Crosslinked polymeric compositions capable of forming continuous matrices for liquid absorbent, semi-interpenetrating polymer networks. These networks are blends of polymers wherein at least one of the polymeric components is crosslinked after blending to form a continuous network throughout the bulk of the material, and through which the uncrosslinked polymeric components are intertwined in such a way as to form a macroscopically homogeneous composition. The compositions of this invention can be used to form durable, ink absorbent, transparent graphical materials.
