Abstract

METODO PARA PREPARAR EMULSIONES FOTOGRAFICAS QUE HAN DE SENSIBILIZARSE EN LA REGION INFRARROJA DEL ESPECTRO ELECTROMAGNETICO, UTILIZANDO COLORANTES SENSIBILIZANTES.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE SENSIBILIZAN GRANOS DE HALOGENURO DE PLATA MEDIANTE SENSIBILIZACION CON AZUFRE O CON ORO; SEGUNDA, SE AN/ADE A LOS GRANOS SENSIBILIZADOS, PARA FORMAR UNA EMULSION, UN COLORANTE DE C NA QUE INCLUYE DOS NUCLEOS HETEROCICLICOS QUE CONTIENEN NITROGENO Y QUE ESTAN UNIDOS ENTRE SI A TRAVES DE UNA CADENA DE METINOS CONJUGADOS; Y POR ULTIMO, SE DIGIEREN DICHOS GRANOS Y SE APLICA COMO RECUBRIMIENTO SOBRE UN SUSTRATO LA EMULSION FORMADA.
