Abstract

LOS DOS TIPOS DE MODIFICACION DE CRISTALES MEJORADOS DE 2-MTOLUIDINA-3-METIL-6-DI-N-BUTILAMINOFLUORANO, ASI COMO EL ADUCTO DE TOLUENO CRISTALINO DEL MISMO PRESENTAN UNA SOLUBILIDAD ELEVADA EN SOLVENTES DE FASE INTERIOR. LOS MATERIALES DE REGISTRO QUE UTILIZAN ESTOS COMPUESTOS COMO FORMADORES DEL COLOR DONANTES DE ELECTRONES PRESENTAN UN RENDIMIENTO PARTICULARMENTE BUEN EN CUANTO A DISTINTAS CARACTERISTICAS TALES COMO LA BLANCURA DEL FONDO, SU ESTABILIDAD DE ALMACENAMIENTO, REPRODUCCION DE LOS COLORES, SENSIBILIDAD A LA FORMACION DE LOS COLORES Y ESTABILIDAD DE ALMACENAMIENTO DE LAS IMAGENES.
