Abstract
Abstract A radiation imageable composition in which an image can be produced upon exposure to intense radiation is disclosed which comprises (a) hollow, ceramic microspheres, and (b) a binder material which will not be destroyed during exposure of the composition to intense radiation and will not mask the image produced upon exposure to intense radiation, wherein the binder material has an index of refraction greater than the index of refraction of the microspheres in the absence of any other dye or pigment.
