Dye sublimation ready coating for low temperature plastic substrates
11731447 · 2023-08-22 · ·

It is the object of the present invention to provide a new polymer coating for low temperature plastics and plastic foams that allows for the application of disperse dyes in a sublimation process that preserves the original properties of the underlying plastic substrate. The composition includes an optically clear synthetic organic polymer base holding two layers, a first reflective layer supported by the low temperature plastic substrate that includes IR radiation reflecting additives, and a second layer supported by the first layer having light scattering particulate additives. The disperse dyes utilized in the invention may include additives to absorb IR radiation provided by an external IR source positioned above the disperse dyes causing the dyes to sublimate and diffuse quickly into the light scattering layer. The combination of these layers allows for diffusion of the disperse dye ink into the light scattering layer while protecting the low temperature plastic below.
