Abstract
The invention relates to a radiation-curable printing medium based on a thermoplastic polymer and at least one radiation-curable monomeric compound. By means of a compound which comprises a heterocyclic ring, it is possible to achieve a favourable combination of properties comprising reactivity and flexibility of the decoration. Preferred monomeric compounds contain a 1,3-dioxolane or 1,3- or 1,4-dioxane ring, and an acrylic or methacrylic group is attached in the manner of an ester around a methylol group. The invention also provides transfers containing the printing medium and decorative preparations.
Claims12
A radiation-curable printing medium for the production of ceramic decoration comprising a polymeric thermoplastic binder and at least one radiation-curable monomeric compound from the range of olefinic compounds containing a heterocyclic ring, the polymeric binder being soluble in the monomeric compound, characterised in that the heterocyclic ring contains 4 to 8 ring members and one or more nitrogen and/or oxygen atoms as heteroatom, at least one radiation-polymerisable vinyl, acrylic or methacrylic group is attached to the heterocyclic ring directly or via a one- to six-membered bridging member, a carbon atom adjacent to a ring heteroatom comprises at least one abstractable hydrogen atom, and N-vinylpyrrolidone and tetrahydrofurfuryl (meth)acrylate are excluded as a olymerisable monomeric compound.
