Abstract
A ceramic decal assembly containing a ceramic substrate, a layer of adhesive contiguous with the substrate, and a ceramic decal contiguous with the layer of adhesive.
Claims23
A ceramic decal assembly comprised of a substrate, a layer of adhesive contiguous with said substrate, and a ceramic decal contiguous with said layer of adhesive, wherein:
- (a) said substrate is selected from the group consisting of a glass substrate, a ceramic substrate, and a glass-ceramic substrate;
- and mixtures thereof, and
- (b) said layer of adhesive has a thickness of less than about 100 microns, and is comprised of at least about 95 weight percent of carbonaceous material;
- and
- (c) said ceramic decal is comprised of an imaged transferable covercoat wherein:
- 1. said imaged transferable covercoat is comprised of at least about 25 weight percent of carbonaceous thermoplastic material;
- 2. said imaged transferable covercoat is comprised of moieties selected from the group consisting of opacification particles, colorant particles, and mixtures thereof, wherein said moieties have a particle size distribution such that at least about 90 weight percent of said moieties are within the range, of from about 0.2 to about 30 microns;
- 3. said imaged transferable covercoat is comprised of film-forming glass flux;
- 4. said moieties have a first concentration in said imaged transferable covercoat and said film-forming glass flux has a second concentration in said image transferable covercoat, the ratio of said first concentration to said second concentration is no greater than about 1.25.
