Abstract
The present invention relates to systems and methods for forming images in solid surfaces, and to solid surfaces containing an image. In particular, the present invention provides systems and methods for forming images in polymeric materials, and polymeric materials containing an image with novel optical density characteristics.
Claims19
An article of manufacture comprising:
- a) a filled polymeric material comprising a polymer component and an inorganic filler;
- and
- b) a fixed image, wherein said fixed image is formed in said filled polymeric material, and wherein said fixed image has a fixed image optical density value within 1.5 of a corresponding transfer image optical density value.
An article of manufacture comprising:
- a) a filled polymeric material comprising a polymer component and an inorganic filler;
- and
- b) a fixed image, wherein said fixed image is formed in said filled polymeric material, and wherein said fixed image has a fixed image optical density value of at least 0.7.
An article of manufacture comprising:
- a) a filled polymeric material comprising polymethyl methacrylate and alumina trihydrate, wherein 20-45 percent by weight of said filled polymeric material is said polymethyl methacrylate, and wherein 55-80 percent by weight of said filled polymeric material is said alumina trihydrate;
- and
- b) a fixed image, wherein said fixed image is formed in said filled polymeric material, and wherein said fixed image has a fixed image optical density value of at least 0.7.
