Abstract

L'INVENTION CONCERNE UN PROCEDE DE MATAGE DES MATERIAUX PHOTOGRAPHIQUES, EN PARTICULIER DES COUCHES D'HALOGENURE D'ARGENT, DES COUCHES DE PROTECTION OU DES COUCHES DE NITROCELLULOSE AU MOYEN DE DISPERSIONS DE POLYMERE. ON UTILISE A CET EFFET DES DISPERSIONS A BASE DE CHLORURE DE POLYVINYLE OU DE COPOLYMERISATS DE CHLORURE DE VINYLE, OBTENUES PAR POLYMERISATION EN MICRO-SUSPENSION OU PAR ENSEMENCEMENT. LES COUCHES MATEES CONTIENNENT LES PARTICULES DE POLYMERE EN UNE CONCENTRATION DE 5 A 50 EN POIDS, DE PREFERENCE DE 7,5 A 20 EN POIDS, PAR RAPPORT AU POIDS SEC DU LIANT. LE PROCEDE FOURNIT DES DISPERSIONS DE MATAGE AYANT LA GRANULOMETRIE DESIREE ET DANS UNE ETROITE REPARTITION GRANULOMETRIQUE, SANS UTILISATION DE DISPOSITIFS DE DISPERSION A GRANDE VITESSE. ON OBTIENT AINSI UNE RUGOSITE EFFICACE POUR UNE DIMENSION PARTICULAIRE DE 0,1 A 5MM MEME POUR UNE FAIBLE CONCENTRATION EN AGENT DE MATAGE. L'INDICE DE REFRACTION DES POLYMERISATS, AVEC UNE VALEUR DE 1,538, CORRESPONDANT PRATIQUEMENT A CELUI DE LA GELATINE, ON EVITE LES PHENOMENES DE TROUBLE ET LES PERTES DE FINESSE. LE PROCEDE EST APPROPRIE A LA PRODUCTION DE MATERIAUX EN NOIR ET BLANC AINSI QUE DE MATERIAUX "COULEUR".THE INVENTION RELATES TO A PROCESS FOR MATTING PHOTOGRAPHIC MATERIALS, IN PARTICULAR SILVER HALOGENIDE LAYERS, PROTECTIVE LAYERS OR NITROCELLULOSE LAYERS BY MEANS OF POLYMER DISPERSIONS. DISPERSIONS BASED ON POLYVINYL CHLORIDE OR VINYL CHLORIDE COPOLYMERISATES, OBTAINED BY POLYMERIZATION IN MICRO-SUSPENSION OR BY SEEDING, ARE USED FOR THIS EFFECT. THE MATTED LAYERS CONTAIN THE POLYMER PARTICLES IN A CONCENTRATION OF 5 TO 50 BY WEIGHT, PREFERABLY 7.5 TO 20 BY WEIGHT, BASED ON THE DRY WEIGHT OF THE BINDER. THE PROCESS PROVIDES MATAGE DISPERSIONS HAVING THE DESIRED GRANULOMETRY AND IN A NARROW GRANULOMETRIC DISTRIBUTION, WITHOUT THE USE OF HIGH SPEED DISPERSAL DEVICES. AN EFFECTIVE ROUGHNESS IS THUS OBTAINED FOR A PARTICULAR DIMENSION OF 0.1 TO 5 MM EVEN FOR A LOW CONCENTRATION OF MATTING AGENT. THE REFRACTION INDEX OF POLYMERISATES, WITH A VALUE OF 1.538, CORRESPONDING PRACTICALLY TO THAT OF GELATIN, WE AVOID THE PHENOMENA OF TROUBLE AND LOSS OF FINESSE. THE PROCESS IS SUITABLE FOR THE PRODUCTION OF BLACK AND WHITE MATERIALS AS WELL AS "COLOR" MATERIALS.
