First Claim
Patent Images
1. 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.
