Abstract:
1. A liquid radiation and thermally curing composition characterized in that said composition comprises a) at least one monoacrylate or monomethacrylate of a 2-alkyl-2-hydroxyalkyl-1,3-propanediol, a mono- or di-acrylate or methacrylate of a 2,2-dihydroxyalkyl-1,3-propanediol, a mono- or di-acrylate or methacrylate of a dimer of a 2-alkyl-2-hydroxyalkyl-1,3-propanediol, a mono-, di-, tri- or tetra-acrylate or methacrylate of a dimer of a 2,2-dihydroxyalkyl-1,2-propanediol, a mono-, di-, tri-, tetra-acrylate or methacrylate of a trimer of a 2-alkyl-2-hydroxyalkyl-1,3-propanediol or mono-di-, tri-, tetra-, penta- or hexa-acrylate or methacrylate of a trimer of a 2,2-dihydroxyalkyl-1,3-propanediol, or an ester between at least one dendritic polyalcohol and acrylic or methacrylic acid, b) at least one crosslinking agent for hydroxyl functional compounds, which crosslinking agent optionally has at least one olefinic double bond, and c) an additive package comprising at least one photoinitiator, radical scavenger, light stabilizer, wetting agent and/or leveling agent, and optionally d) at least one monomeric or oligomeric reactive diluent.
