摘 要：

PURPOSE: To obtain the Fresnel lens which is well transferable from lens molds and has excellent optical performance by uniformly dispersing a specific amt. of a noncrosslinked resin which can be

extracted by an org. solvent into a styrene crosslinked resin. ;CONSTITUTION: The noncrosslinked resin which can be

extracted by the org. solvent is uniformly dispersed at 3 to 50wt.% of the entire part into the styrene resin. The moldability of the resin compsn. is lost if the

noncrosslinked resin component is below 3wt.%. The strength of the resin compsn. is insufficient if the component exceeds 50wt.%. The styrene crosslinked resin refers to the resins which can be obtd. by polymerizing with a styrene monomer and other monofunctional monomers which are copolymerizable therewith at need and multifunctional monomers and which do not dissolve in org. solvents. The noncrosslinked resin which can be

extracted by the org. solvent refers to so-
