Electrophoretic media
First Claim
1. An electrophoretic medium consisting essentially of an aqueous gel formed by polymerization in the presence of aqueous medium and in the absence of oxygen of one or more acrylamide monomers in the presence of one or more different crosslinking or comonomer agents selected from the group consisting of diethyleneglycol diacrylate, diacetone acrylamide, pentaerythritolacrylate, 1,3-butyleneglycol diacrylate, tetraethylene glycol diacrylate, bisacrylamide methylether and tris-(2-hydroxyethyl)isocyanurate triacrylate.

Abstract
Electrophoretic media based on polymers with novel structures are disclosed. The polymers are formed by polymerization of acrylamide monomers, such as N-methylolacrylamide, with cross-linking agents or comonomer agents such as tetraethylene diacrylate and bisacrylamide methylether.
