Patent ID: 6885505

Claim:
In a gobo for projecting a pattern in several colors wherein the color-separated and rastered single-color components of the pattern are each reproduced in the gobo in a dichroic surface-coating corresponding to respective colors and disposed on a transparent substrate comprising a plurality of mutually superimposed disc-shaped and transparent substrates, each substrate having disposed thereon a dichroic surface-coating for forming a color filter; whereby combinations of the color filters are capable of reproducing the colors of the multi-color pattern; and that respective color-emitting surface coatings present a pattern that coincides with the pattern for corresponding color components in the multi-color pattern, said gobo further including a substrate that has a total-blocking surface coating in a pattern corresponding to the contrast of the multi-color pattern; and in that each substrate has a surface coating on only one side of the substrate; the improvement comprising: each of the plurality of substrates bonded over the entirety of every surface contiguous to another facing substrate, whereby the gobo is an integrally bonded structure.
