Abstract

1470619 Electro-photographic materials PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 13 March 1975 [16 May 1974] 10432/75 Heading G2C An electro-photographic material comprises one or more photo-conductive polyphenylenevinylenes and one or more 1, 4- bis (styryl) benzene derivatives as sensitizers, preferably on a conductive support. The styryl benzenes are preferably of Formula: wherein at least one of R 7 and R 8 is cyano and the remaining radicals are H, cyano, halogen, nitro, amino, alkyl, aryl or alkoxy groups. A silicone varnish may be added to the electro-photographic layer. The polyphenylenevinylenes used may be those of Specification 1345692.

Description

Преимуществом полученного электрофотографического материала  вл етс  то, что подобные смешанные слои легко получить из смешанных растворов , а в специальных случа х из сплавов, а добавки/ повышающие чувствительность , ввод т относительно в больших количествах без видимого расслоени  полимеров, благодар  чему образуютс  прозрачные слои. Кроме того, повышаетс  химическа  стабильность и стабильность при хранении.The advantage of the obtained electrophotographic material is that such mixed layers are easily obtained from mixed solutions, and in special cases from alloys, and additives / sensitivity enhancements are introduced relatively in large quantities without visible stratification of polymers, due to which transparent layers are formed. In addition, chemical and storage stability is improved.

Получение электрофотографического материала иллюстрируетс  следующими примерами.The preparation of the electrophotographic material is illustrated by the following examples.

Этот раствор нанос т на провод щий субстрат и после испарени  растворител  при 30115 С получают прозрачный фотопроводниковый слой толщиной около 2 мкм. Подобный слой можно зар дить с помощью короны до 350 В. При освещении 40 люкс в течение 1 с этот слой разр дитс  до половины потенциала.Example 1. 9.64 g of polyxylylidene (mol. 2500 g / mol) is dissolved in 300 ml of chloroform and stirred with a solution of 0.36 g of 1 4-bis- (c-cyanosryryl) -2, B-dimethoxybenzene in 200 ml of toluene. This solution is applied to a conductive substrate and, after evaporation of the solvent at 30115 ° C, a transparent photoconductor layer is obtained with a thickness of about 2 microns. Such a layer can be charged with a corona up to 350 V. If it is illuminated at 40 lux for 1 s, this layer discharges to half the potential.
