More particularly, the present invention relates to a functional coating material having regression reflection function and optical and roughness control. More specifically, the present invention relates to a functional coating material comprising a mixture of a white resin and a diluent, adding a urethane binder, adding beads of 1500 to 2000 mesh, A metal powder and a curing agent, and a functional coating material capable of adjusting light and illumination. Therefore, the present invention according to the present invention has a regression reflection function by using a composition that satisfies a special functional paint for controlling the regression reflection function and light / roughness, and it is possible to control directness, lightness and illuminance, But also the bonding property on a smooth surface is enhanced, and a paint excellent in non-shrinking property can be provided.
