Liquid sorbent materials

The invention relates to composite, liquid-sorbent media which can be applied to various substrates to provide improved liquid-sorbent materials. The composite media comprise a liquid-sorbent underlayer (9) and, overlying said underlayer (9), a liquid-permeable surface layer (7), the liquid sorptivi...

Zusammenfassung:	The invention relates to composite, liquid-sorbent media which can be applied to various substrates to provide improved liquid-sorbent materials. The composite media comprise a liquid-sorbent underlayer (9) and, overlying said underlayer (9), a liquid-permeable surface layer (7), the liquid sorptivity of said underlayer being greater than the liquid sorptivity of said surface layer. Transparent sheets (7) having the liquid-sorbent composite media coated on the surface are described as a preferred embodiment of the invention.
