Claims20
An article comprising:
- a) a light transmissive substrate having a surface layer comprising the reaction product of
- i) at least one fluoropolyether (meth)acryl compound that comprises at least one terminal F(CF(CF3)CF2O)aCF(CF3)— group and at least two (meth)acryl groups;
- wherein a averages from 4 to 15;
- and
- ii) at least one non-fluorinated crosslinking agent;
- and
- b) a hardcoat layer disposed between the substrate and the surface layer.
A display panel comprising:
- a) a light transmissive substrate having a surface layer comprising the reaction product of
- i) at least one fluoropolyether (meth)acryl compound that comprises at least one terminal F(CF(CF3)CF2O)aCF(CF3)— group and at least two (meth)acryl groups;
- wherein a averages from 4 to 15;, and
- ii) at least one non-fluorinated crosslinking agent;
- and
- b) a hardcoat layer disposed between the substrate and the surface layer.
