A dual coating is provided for tinting a plastic material such that the plastic material is tinted and rendered scratch resistant. Also provided is tintable, scratch resistant plastic materials and tinted, scratch resistant plastic materials. The dual layer coating includes a dye reservoir layer formed over a surface of the material to be tinted and a hard coating layer formed over the dye reservoir layer. The dye reservoir layer includes between about fifteen and eighty percent by weight of a flexible acrylated oligomer or acrylated oligomer/acrylate monomer blend resin, and between about one and seventy percent by weight of a mono vinyl functional reactive diluent. The hard coating layer formed over the dye reservoir layer includes between about twenty and one hundred percent by weight of alkane polyols, the alkane polyols containing up to about forty eight carbon atoms and at least three O-[acryloyl(polyalkylene oxide)] groups, each polyalkylene oxide chain including between about one and twenty alkylene oxide groups, and between about ten and seventy percent by weight of polyacryloylated alkane polyols, the alkane polyols containing up to about twenty four carbon atoms and at least about two O-acryloyl groups.
