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.
Claims19
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 that is radiation-curable;
- and
- at least one photoinitiator;
- wherein said at least one poly(meth)acrylate compound comprising at least 6 (meth)acrylate groups and said at least one radiation-curable unsaturated silane compound represent at least 95% of the weight of polymerizable compounds present in the composition;
- and
- the radiation-curable unsaturated silane compounds are present in an amount higher than or equal to 30% by weight, as compared to the composition total weight.
