A substantially solid, transparent, photopolymerizable composition that forms a refractive-index image upon exposure to actinic radiation as the sole processing step, said composition having a refractive index modulation greater than approximately 0.01 when imaged and consisting essentially of: (a) approximately 25 to 90% of a solvent soluble, fluorine-containing polymeric binder; (b) approximately 5 to 60% of a liquid ethylenically unsaturated monomer, said monomer having a boiling point above 100°C. and being capable of addition polymerization; (c) approximately 0 to 25% of a plasticizer; and (d) approximately 0.1 to 10% of a photoinitiator system that activates polymerization of said unsaturated monomer upon exposure to actinic radiation; wherein said percentages are weight percentages of the total composition.
