Abstract
An optical element which comprises a liquid crystal dispersion film layer which is composed of a spongy matrix polymer and a liquid crystal such that they become separated at use temperatures and mixed at high temperatures. The mixture remains mixed upon quenching but gets phase separated upon slow cooling. The optical element produces an electro-optic effect and permits heat-mode recording.
