    摘要: The present invention relates to optical elements comprising fluorochemical surface treatments. The invention further relates to articles such as retroreflective sheetings, pavement markings and beaded projection screens comprising a binder and the surface treated optical elements. The surface treatment comprises at least one fluoropolymer selected from a) fluoropolymers comprising a fluorinated hydrocarbon backbone and side chains comprising at least one of fluoroalkyl, fluoroether alkyl, fluoroalkoxy and mixtures thereof; and b) fluoropolymers comprising a hydrocarbon backbone and side chains comprising at least one of fluoroether alkyl, fluoroalkoxy and mixtures thereof.

    摘要: This invention concerns a process for modifying a polymeric substrate by contacting the surface with a photoreactive solution of an inorganic photochemical electron donor while irradiating the surface with actinic radiation. Patterns of modified and unmodified surfaces can be produced. Polymeric substrates with modified surfaces may be effectively bonded to polymer films to form composite articles. The process has particular applicability to the surface modification of fluorinated polymers.
