    摘要: Provided are an indicating material having excellent facility and high security and an indicating method for recording and indicating information on this indicating material. The indicating material has a structure that an ultraviolet light-screening layer having visible light-transmitting ability is laminated on a recording layer having visible light-transmitting ability and composed of a recording layer-forming material containing a color-developing component that becomes a color-developed state by the action of ultraviolet light. The indicating method is an indicating method for recording and indicating information on the above-described indicating material, comprising condensing a laser beam having a wavelength of a visible range or longer on the recording layer in the indicating material to irradiate the recording layer with the laser beam and recording and indicating the information by two-photon absorption.

    摘要: An optical memory medium having a transparent substrate, a recording layer and a reflective layer, the recording layer and the reflective layer being formed in this order on the transparent substrate. The recording layer is a diarylethene derivative dispersed in a non-polar polymeric binder. The optical memory medium with such a recording layer fully utilizes advantageous properties of the diarylethene derivative, such as good thermal stability of recorded state, excellent durability against repeated color changes between colored and colorless states, and photosensitive property to semiconductor laser light with a wavelength of 780 nm. The optical memory medium enables high-density recording and non-destructive readout.

    摘要: Disclosed is light-driven actuator element characterized in that, inter alia, it can be reduced to micrometer size, is rapidly responsive, and reversibly changes to enable repeated use. The light-driven actuator element includes a crystal of diarylethene compound which changes shape upon photoisomerization (e.g., the compound of Structural Formula (I) below, where R1 represents a hydrogen atom or methyl group and R2 represents a methyl group). The element can be a rod-shaped or plate-like microcrystal having a size on the order of micrometer. The element bends (or contracts) on irradiation with ultraviolet light and expands to return to the original size on irradiation with visible light.
