Abstract

UNA COMPOSICION FOTOCROMATICA CONTIENE POR LO MENOS DOS COMPUESTOS FOTOCROMATICOS, DEFINIDOS POR LA FORMULA GENERAL: (FIG. A), DONDE LOS DISTINTOS SUSTITUYENTES DE R1-R7 Y X SON COMO SE DEFINEN EN LA ESPECIFICACION. EN TAL MEZCLA, POR LO MENOS UN COMPUESTO FOTOCROMATICO SE DEFINE POR LA FORMULA GENERAL, DONDE R7 REPRESENTA UN ATOMO DE HIDROGENO Y POR LO MENOS OTRO COMPUESTO TAMBIEN SE DEFINE POR LA FORMULA GENERAL, DONDE R7 REPRESENTA UN GRUPO -NR8R9, DONDE R8 Y R9 TIENEN EL SIGNIFICADO DEFINIDO EN EL TEXTO.A PHOTOCHROMATIC COMPOSITION CONTAINS AT LEAST TWO PHOTOCHROMATIC COMPOUNDS, DEFINED BY THE GENERAL FORMULA: (FIG. A), WHERE THE DIFFERENT SUBSTITUTES FOR R1-R7 AND X ARE AS DEFINED IN THE SPECIFICATION. IN SUCH A MIX, AT LEAST ONE PHOTOCHROMATIC COMPOUND IS DEFINED BY THE GENERAL FORMULA, WHERE R7 REPRESENTS AN HYDROGEN ATOM AND AT LEAST ANOTHER COMPOUND IS DEFINED BY THE GENERAL FORMULA, WHERE R7 REPRESENTS A GROUP -NR8R9 THEY HAVE THE MEANING DEFINED IN THE TEXT.
