  • Dulled radiation-sensitive recording material and process for its production
    Patent number: 5994029
    Abstract: The invention relates to a sheet-like radiation-sensitive recording material whose surface is a discontinuous dulling layer comprising monodisperse particles is present. The dulling layer can be produced by spraying on a dulling liquid. An apparatus comprising an oscillation generator, which can transmit oscillations to the liquid in the apparatus, and has an orifice plate which has at least one hole with a diameter of from 5 to 250 .mu.m and from which the liquid emerges in the form of at least one laminar free jet which disintegrates into monodisperse drops is suitable for this purpose. The oscillation generator is preferably a piezoelectric ceramic.
