Claims20
A electromagnetic energy-absorbing optical product comprising:
- a) a polymeric substrate and
- b) a composite coating, said composite coating comprising a first layer comprising a polyionic binder and a second layer comprising a electromagnetic energy-absorbing insoluble particle, wherein each of said first layer and said second layer include a binding group component which together form a complimentary binding group pair.
A method for forming an electromagnetic energy-absorbing optical product, said method comprising:
- a) applying a first coating composition to a polymeric substrate to form a first layer, said composition comprising a polyionic binder;
- and
- b) applying a second coating composition atop said first layer to form a second layer, said second coating composition comprising at least one pigment;
- wherein each of said first layer and said second layer include a binding group component which together form a complimentary binding group pair.
