Abstract:
A method for producing a decorative floor covering comprises digitally printing an adhesive on a printing substrate thus generating an adhesive layer forming an at least one-dimensionally patterned decorative motif. The adhesive is a radiation-curable composition, preferably essentially free from non-reactive solvents and/or from photoinitiator. The printing substrate includes one of a core structure and a wear layer. After the printing of the adhesive, the adhesive layer on the printing substrate is contacted with the other one of the core structure and the wear layer. The core structure and the wear layer are then attached to each other by electron-beam curing the adhesive layer between them.
