Abstract

UNA CAPA SUSCEPTIBLE DE FORMAR IMAGENES, QUE COMPRENDE A) UN AGLUTINANTE QUE ES UNA RESINA ORGANICA QUE NO SE DESCOMPONE NI PIERDE SU INTEGRIDAD ESTRUCTURAL A 93°C DURANTE 30 SEGUNDOS SELECCIONADA ENTRE ESTERES DE CELULOSA; B) UN COLORANTE SELECCIONADO ENTRE UN COLORANTE BLANQUEABLE Y UN COLORANTE LEUCO, SIENDO SELECCIONADO EL COLORANTE BLANQUEABLE ENTRE LOS SIGUIENTES: METINOS, ANTRAQUINONAS, INDIGRIDES, XANTENOS, AZINAS, OXOZINAS, TIAZINAS, AZOS, DIAZOS, TRIARILMETANOS, INDAMINAS Y COLORANTES CON LAS SIGUIENTES FORMULAS (I) Y (II). EL COLORANTE LEUCO SE SELECCIONA ENTRE TRIARILMETANOS, ESTIRILOS, OXANOS Y TRIAZINAS; C) UNA SAL DE NITRATO METALICAS O SALES METALICAS HIDRATADAS O NITRATO DE AMONIO Y NITRATO DE AMONIO CERICO; D) UNA SAL DE DIAZONIO DE FORMULA GENERAL AR-(N=N)+ X- DONDE AR-N=N REPRESENTA UN NUCLEO AROMATICO FOTOSENSIBLE Y PRODUCTOS DE CONDENSACION DE LAS SALES CON FORMALDEHIDO, X' REPRESENTA UN ANION, HALLANDOSE EL COLORANTE LEUCO POR LO MENOS EN0,3% O EL COLORANTEÑ BLANQUEABLE EN UNA CANTIDAD SUFICIENTE PARA QUE HAYA UNA DENSIDAD OPTICA DE POR LO MENOS 0,1 EN LA CAPA. EL NITRATO EN UNA RELACION MOLAR DE 0,1 A 1,0 RESPECTO AL COLORANTEY LA SAL DE DIAZONIO POR LO MENOS AL 0,1% EN PESO DE LA CAPA Y EL AGLUTINANTE, AL MENOS AL 25%.A SUSCEPTIBLE LAYER OF FORMING IMAGES, WHICH INCLUDES A) A BINDER THAT IS AN ORGANIC RESIN THAT DOES NOT DECOMPOSE OR LOSES ITS STRUCTURAL INTEGRITY AT 93 ° C FOR 30 SECONDS SELECTED BETWEEN CELLULOSE ESTERS; B) A DYE SELECTED BETWEEN A BLEACHABLE DYE AND A LEUCO DYE, THE BLEACHABLE DYE BEING SELECTED AMONG THE FOLLOWING: METINOS, ANTRAQUINONAS, INDIGRIDES, XANTENAS, OXOZINS, TIAZINAS, AZOS, AZOS (I) AND (II). LEUCO COLOR IS SELECTED FROM TRIARILMETHANES, STYRILS, OXANES AND TRIAZINES; C) A METALLIC NITRATE SALT OR HYDRATED METALLIC SALTS OR AMMONIUM NITRATE AND CERAMIC AMMONIUM NITRATE; D) A DIAZONIUM SALT OF GENERAL FORMULA AR- (N = N) + X- WHERE AR-N = N REPRESENTS A PHOTOSENSITIVE AROMATIC NUCLEUM AND SALT CONDENSATION PRODUCTS WITH FORMALDEHYDE, X 'REPRESENTS AN ANION, FINDING THE LEUCO DYE AT LEAST 0.3% OR THE COLORANTEÑ WHITABLE IN A QUANTITY ENOUGH FOR THERE IS AN OPTICAL DENSITY OF AT LEAST 0.1 IN THE LAYER. NITRATE IN A MOLAR RATIO OF 0.1 TO 1.0 REGARDING COLOR AND DIAZONIUM SALT AT LEAST 0.1% BY WEIGHT OF THE LAYER AND THE BINDER, AT LEAST 25%.
