Abstract
The present invention relates to a curable coating composition, especially a radiation curable coating composition comprising at least one poly(meth)acrylate compound comprising at least 6 (meth)acrylate groups, at least one unsaturated silane compound, and at least one photoinitiator. Said at least one poly(meth)acrylate compound comprising at least 6 (meth)acrylate groups and said at least one unsaturated silane compound represent at least 95% of the weight of polymerizable compounds present in the composition. Upon radiation-curing, the composition provides an abrasion- and/or scratch-resistant coating.
