Abstract
A cyanine pigment and a polyvinylalcohol are dissolved into a water to make a mezzo-J-association body dispersed solution. Then, the mezzo-J-association body dispersed solution is maintained at a high viscosity by holding the solution at a given temperature. Subsequently, the mezzo-J-association body dispersed solution is dropped onto a given substrate and thereafter, rubbed. Thereby, the J-association body oriented dispersion film having the J-association bodies composed of the associated and oriented cyanine pigments in polarization can be obtained.

A J-association body oriented dispersion film comprising a matrix and oriented mezzo-J-association bodies, each having 50-10000 molecules, in the matrix.
A method for producing a J-association body oriented dispersion film comprising the steps of:
- preparing a mezzo-J-association body dispersed solution having a high viscosity in which mezzo-J-association bodies, each having 50-10000 molecules, are incorporated, and
- rubbing the mezzo-J-association body dispersed solution to orient the mezzo-J-association bodied in polarization in a matrix.
A method for producing a J-association body oriented dispersion film comprising the steps of:
- preparing a mezzo-J-association body dispersed solution having a high viscosity, composed of water, aqueous polymer and mezzo-J-association body which are dissolved in the water,
- dropping the mezzo-J-association body dispersed solution on a substrate, and
- rubbing the dropped dispersion solution to orient the mezzo-J-association body in polarization in the matrix made of the aqueous polymer.
