Abstract

Elementi fotografici sensibili all'infrarosso comprendono un supporto opaco, uno strato di emulsione agli alogenuri d'argento sensibilizzata all'infrarosso e uno strato protettivo di colloide idrofilo su una faccia del supporto, detto strato protettivo comprendente silice colloidale avente dimensioni medie delle particelle inferiori a 15 m?.Gli elementi hanno una aumentata latitudine di esposizione per esposizione a diodi laser infrarossi, e una maggiore densità massima dopo trattamento fotografico.
