Abstract:
A method for forming a colored multilayer composite by applying at least two (or more) radiation-curable layers to flexible supporting layers made of film web or paper web and laminating the supporting layers to each other, whereby the radiation-curable layers contain color pigments, comprising the following steps:bringing together the two flexible supporting layers with the radiation-curable layers facing toward one another; pressing together the two flexible supporting layers with exposure to heat to form the colored multilayer composite; partially curing the radiation-curable layers within the multilayer composite in a first step applying not more than 30% of the maximum dose of actinic radiation required for complete curing of the radiation-curable layers; removing one of the supporting layers from the colored multilayer composite; and completely curing the radiation-curable layers in a second step using a dose of from 30% to 100% of the actinic radiation for full curing.
