Films that undergo a reversible change from opaque to transparent states by the action of temperature have many practical uses. Organic crystals dispersed in thermosetting polymers have been employed but present several disadvantages. The addition of a small amount of a thermoplastic polymer with a refractive index matching those of the two other components produces films of excellent optical properties consisting of thermoplastic/organic crystal domains dispersed in the polymer network
