    摘要： Novel laser-optical recording elements which can be repeatedly erased and recorded on contain recording layers (a) which exhibit enantiotropic, ferroelectric smectic liquid crystalline (S.sub.c*) behavior, so that they can be switched back and forth between two thermodynamically stable, optically distinguishable ferroelectric smectic liquid crystalline S.sub.c* order states on exposure to a laser beam of sufficient luminous power, by applying an external electric field. The recording layers (a) themselves consist mainly or exclusively of novel polymers P having chiral mesogenic side groups. The novel polymers P are prepared using the novel monomers of the general formula I ##STR1## where R is hydrogen, chlorine or methyl, A is a flexible space-maintaining long-chain molecular moiety, and C is an optically active chiral molecular moiety and B is a mesogenic molecular moiety composed of at least three aromatic nuclei which are bonded linearly or virtually linearly to one another,or they are prepared using the novel monomers I which contain specially selected molecular moieties B in a novel combination with selected molecular moieties C.

    摘要： In a novel process for the reversible or irreversible production of an image by the imagewise action of energy on a recording layer, resulting in a pattern of surface charges which corresponds to the imagewise action of the energy, on the surface of the recording layer, the recording layer used is one which contains or consists of an organic material which solidifies in glassy form, is nonphotoconductive or only slightly photoconductive and has permanent dipoles, wherein the pattern of surface charges is produced, without or almost without formation of free charge carriers, by reversible imagewise orientation of some or all of the permanent dipoles present in the recording layer, with the aid of an electric field applied imagewise. The novel process is advantageously carried out using a novel apparatus which comprises a suitable recording element, apparatus for the imagewise action of an electric field on the recording layer of the recording element and a counter-electrode which is in direct, non-frictional contact with the recording layer and can be removed again therefrom. The pattern of surface charges which is produced by the novel process can be treated with liquid or solid toners. The resulting toner image can then either be fixed on the recording layer or transferred from the recording layer to another surface, after which the pattern of surface charges can be deleted by uniform action of energy. Thereafter, a further image can be produced. In this way, it is possible to produce photocopies without the high voltage sources required in the conventional electrophotographic processes having to be used.

    摘要： A process for the reversible or irreversible production of an image by imagewise exposure of a recording layer to energy in the presence or absence of an electrical and/or magnetic field, resulting in a pattern of surface charges on the surface of the recording layer corresponding to the imagewise exposure to energy. The recording layer consists essentially ofan organic material which solidifies in a glass-like manner, is non-photoconductive or substantially non-photoconductive and contains permanent dipoles, in whichthe pattern of surface charges is produced without or substantially without the formation of free charge carriers by reversible imagewise alignment of at least some of the permanent dipoles present in the recording layer.The process is advantageously carried out using an apparatus which comprises a suitable recording element, devices for imagewise exposure of the recording layer of the recording element to energy, and a counter-electrode which is in direct contact with the recording layer and can be removed therefrom. The pattern of surface charges produced by the process can be toned with liquid or solid toners. The resultant toner image can then either be fixed on the recording layer or transferred from the recording layer to another surface, after which the pattern of surface charges can be erased by exposing the entire surface to energy. A further image can then be produced. In this way, photocopies can be produced without the need to use the high-voltage sources which are necessary in conventional electrophotographic processes.
