Zusammenfassung:An improved image-transmitting synthetic resin rod comprising a reaction product of an acrylic resin ① containing epoxy groups with a material ② having a refractive index 0.15 - 0.35 lower than that of said acrylic resin ①, and distributed in said rod so as to satisfy equation (1):wherein r is the radial distance from the center axis of the rod (0 ≦ r # ro),ro is the radius of the rod,nr is the refractive index at point r,n. is the refractive index at the center of the rod,g is the distribution constant of the refractive index, andh4 and h6 are high order coefficients, and a process for producing the same.
