Abstract: A polymer liquid crystal emulsion includes a liquid crystal and a water soluble copolymer obtained by polymerizing a hydrophilic monomer with one or more hydrophobic monomers. The concentration of the hydrophobic monomer may be 14 to 25% by weight based on the combined weight of the hydrophobic monomer and the hydrophilic monomer. The hydrophobic monomer may be styrene, methyl methacrylate, vinyl acetate, acrylate or methacrylate. The hydrophilic monomer may be acrylamide, acrylonitrile or acryloylchloride. Preferably, the hydrophilic monomer is acrylamide or a derivative thereof and the hydrophobic monomer is styrene, methyl methacrylate or vinyl acetate. The liquid crystal may be a nematic liquid crystal formed of an azomethine compound or an azo compound. The water soluble copolymer, the liquid crystal and water may form a liquid crystal/aqueous polymer solution. In this case, the concentration of the liquid crystal in the liquid crystal/aqueous polymer solution is in the range of 50 to 70% by weight.
