The invention relates to a method for producing cured material consisting of material mixtures that can be cured by actinic radiation, by irradiation with UV-radiation. The invention is characterised in that it uses UV-radiation of the following spectral distribution and dose: wavelength lambda = 400 to 320 nm; dose = 500 to 2,500 mJ/cm2; wavelength lambda = 320 to 290 nm; dose = 700 to 3,000 mJ/cm2; wavelength lambda = 290 to 180 nm; dose = 100 to 500 mJ/cm2.
L'invention concerne un procédé de production de matériaux durcis à partir de mélanges durcissables par un rayonnement actinique et exposés à un rayonnement ultraviolet. L'invention est caractérisée en ce que l'on utilise un rayonnement ultraviolet ayant la répartition spectrale et la dose suivante: longueur d'onde lambda = 400 à 320 nm; dose = 500 à 2.500 mJ/cm2; longueur d'onde lambda = 320 à 290 nm; dose = 700 à 3.000 mJ/cm2; longueur d'onde lambda = 290 à 180 nm; dose = 100 à 500 mJ/cm2.
