The present invention relates to optical elements comprising fluorochemical surface
treatments having the general structure Rf-[G]m(CH2)nX
wherein Rf is a fluorinated alkyl group, G is a divalent linking group selected
from oxygen (O) and sulfonamido (SO2R),
m is an integer ranging from 0 to 1, n is an integer ranging from 1 to 24, and
X is polar group or polar group containing radical. The invention further relates
to materials such as retroreflective sheetings, pavement markings and beaded projection
screens comprising a binder and the surface treated optical elements.
