Abstract

Matière pour diazotypique utile pour produire des contretypes d'originaux à demi-teintes, tels que des films radiographiques. Elle comprend un support pelliculaire transparent comportant un revêtement d'une couche constituée essentiellement d'au moins deux composés diazoïques photosensibles ayant des vitesses de photolyse différentes, des copulants pour les composés diazoïques, une matière absorbant les radiations ultra-violettes et, distribuée d'une matière homogène dans la couche, une proportion d'au moins environ 7 % en poids, par rapport au poids de laque, d'une matière inerte en particules comme de la silice. L'utilisation de cette matière rend possible d'obtenir approximativement une photolyse logarithmique, fournissant ainsi une linéarité suffisante dans la courbe caractéristique correspondante pour que l'on obtienne les résultats désirés de reproduction.
