Abstract

SE PREVE UN FOTORRECEPTOR ELECTROFOTOGRAFICO CON UNA CAPA FOTOSENSIBLE, QUE CONTIENE UN COMPUESTO AZO REPRESENTADO POR LA SIGUIENTE FORMULA GENERAL (1): EN LA QUE A REPRESENTA UN RESIDUO ACOPLADOR QUE TIENE RADICALES OH FENOLICAS, R1 Y R2 DESIGNAN, RESPECTIVAMENTE UN RADICAL DE UN NUMERO ENTERO M = 0-2, N = 0-4, ELEGIDO ENTRE EL GRUPO QUE CONSISTE EN ATOMOS DE HIDROGENO, HALOGENO, GRUPO ALQUILO, GRUPO ALCOXI Y GRUPO AMINO DISUSTITUIDO. EL FOTORRECEPTOR ELECTROGRAFICO DE ESTA INVENCION TIENE EXCELENTES CARACTERISTICAS DE ELECTRIFICACION, CARACTERISTICAS DE SENSITIVIDAD Y PROPIEDAD DE FORMACION DE IMAGENES ASI COMO UNA BUENA SENSITIVIDAD. ADEMAS SUS CARACTERISTICAS DE SENSITIVIDAD Y ELECTRIFICACION EXPERIMENTAN MENOS VARIACIONES INCLUSO CUANDO SE EMPLEAN REPETIDAMENTE. TAMBIEN EXPERIMENTA UNA PEQUEÑA FATIGA INDUCIDA POR LA LUZ. TIENE UNA GRAN CAPACIDAD DE RESISTENCIA A LA INTEMPERIE.
