A process for forming a permanent, abrasion and chemical resistant image on a fabric or plastic substrate is disclosed which comprises (a) providing a printing matrix having raised portions in the shape of the image to be printed on the substrate, (b) providing a carrier supported ink comprising (1) a uniform coating of an ink composition comprising a sublimable dye, (2) a carrier sheet for supporting said coating on one surface thereof, (c) disposing the carrier supported ink adjacent to the printing matrix such that the uncoated surface of the carrier sheet faces the printing matrix, (d) providing a fabric or plastic film substrate having a surface into which said sublimable dye can diffuse, (e) disposing the substrate such that the surface thereof faces the coated surface of the carrier sheet, (f) applying pressure between said printing matrix and said substrate to cause the printing matrix to contact the uncoated surface of the carrier sheet and the coated surface of the carrier sheet to contact the substrate surface, said pressure being applied under conditions sufficient to cause the ink composition to completely transfer from the carrier sheet to the substrate surface in the shape of the image defined by the raised portions of the printing matrix, but insufficient to cause the dye in the ink composition to sublime or vaporize, and (g) heating the ink composition which has been transferred to the substrate surface, and heating occurring under conditions sufficient to cause the dye therein to sublime or vaporize and then diffuse into the substrate surface.

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.
