Abstract
A recording element which comprises a recording layer containing, a first charge-generating material adapted to generate a first electric charge by a supply of external energy, a first charge-transporting material for transporting the first electric charge, a charge-capturing material for capturing the first electric charge, and a material having an electro-optical effect, wherein a change in optical properties of the recording layer is caused only through an inner electric field to be generated by a delivery of electric charge between the first charge-generating material generating electric charge and the charge-capturing material capturing the electric charge.
