Um, no. Reflectors are normally either cube corners (in molded plastic reflectors) or embedded spherical beads (vinyl ribbons and screen-printed fabrics), and both of those are designed to act as ideal retro-reflectors; slight imperfections allow for a small spread of the reflected light, but the spread is only a couple of degrees. Traffic signs and the paint used for lane markings and crosswalks work the same way. Any other arrangement is a diffuser, not a reflector.
