Multi-layered radiation imageable coating

A radiation imageable coating comprising:

• a first thermochromic layer including a bleachable antenna dye;
• a second thermochromic layer including a bleachable antenna dye;
• a third thermochromic layer including a non-bleachable antenna dye;
• a first insulating layer disposed between said first thermochromic layer and said second thermochromic layer;
• a second insulating layer disposed between said second thermochromic layer and said third thermochromic layer;
• wherein said second thermochromic layer is disposed between said first thermochromic layer and said third thermochromic layer;
• wherein an absorbance maximum wavelength of said bleachable dye in said second thermochromic layer is different than an absorbance maximum wavelength of said bleachable dye in said first thermochromic layer;
• wherein said bleachable dye in said second thermochromic layer and said bleachable dye in said first thermochromic layer are both configured to be bleached when exposed to a single known wavelength of light;
• and
• wherein each of said first, second, and third thermochromic layers are each configured to form a different color selected from the group consisting of cyan, magenta, and yellow when exposed to thermal energy.
