Title (EN) FROST IMAGE RECORDING MEDIUM AND METHOD AND APPARATUS FOR PREPARING AND READING FROST IMAGE
(FR) SUPPORT D'ENREGISTREMENT A IMAGE GIVREE ET PROCEDE ET APPAREIL DE PREPARATION ET DE LECTURE D'UNE IMAGE GIVREE
Abstract:
(EN) A data recording medium (10) is manufactured by laminating an electrode (13) and a recording layer (11) of a pinene polymer having a molecular weight of 500 $m(k) 10,000 on a support (15). By thermal development, a thermally stable frost image can be produced without causing attenuation of data charge generated on the resin surface. Transmitted or reflected light can be accordingly used for reproduction of the frost image, without provision of a photoconductive layer coloration of which has bad influence. Since voltage impression exposure is made, the degree of uneveness of the frost image changes in accordance with the exposure value. Therefore, a tone wedge effect can be provided and high resolution can be obtained. It is thus possible to produce high-quality and high-fidelity OHP transparencies, microfilms, slide films, and so forth.
(FR) On fabrique un support d'enregistrement (10) de données en feuilletant sur un support (15) une électrode (13) et une couche d'enregistrement (11) en polymère de pinène possédant un poids moléculaire de 500 $m(k) 10 000. Grâce au développement thermique, l'on peut former une image givrée thermostable sans atténuer la charge de données générée à la surface de la résine. On peut donc utiliser de la lumière émise ou réfléchie pour reproduire l'image givrée sans avoir recours à une couche photoconductrice dont la coloration a une influence néfaste. Dès que la lumination par tension appliquée a été réalisée, le degré d'inégalité de l'image givrée change en fonction de l'indice de lumination. On peut donc obtenir des diapositives OHP, des microfilms, des films diapositifs ou analogue de haute qualité et de haute fidélité.
