  • Patent number: 11286396
    Abstract: A multi-layer coating that transmits and reflects light can include a first coating layer and a second coating layer applied over the first coating layer. The first coating layer is prepared from a coating composition that includes a film forming resin, crosslinked organic particles, and inorganic pigment particles. The crosslinked organic particles and the inorganic pigment particles each have a refractive index that is different from the refractive index of the film forming resin. The second coating layer is prepared from a coating composition that includes a film forming resin and reflective and/or translucent particles.
