PURPOSE: To repeatedly perform the display recording and erasure of an image, to provide sufficient image density at a time of the projection by an overhead projector and to reduce the deterioration of image density caused by the repetition of the display recording and erasure of the image. CONSTITUTION: In a reversible display recording OHP sheet obtained by providing a display recording layer on a light pervious base material and capable of reversibly performing the display recording and erasure of an image, the display recording layer is formed of a compsn. containing a polymeric liquid crystal composed of a copolymer consisting of at least two components, that is, a mesogen monomer unit and a non-mesogen monomer unit. This compsn. has a multidomain structure therein and is crosslinked. The domain diameter showing the max. of the domain distribution in the multidomain structure is pref. within a range of 0.7-2μm. The control of the multidomain structure in the display recording layer is performed by applying heat treatment before crosslinking. |
