col to tex

hi
I made an own material and have it assigned to my model.
Then I have colored a model by Polypainting.

So I finished, I created a white texture.
Then, as always, I wanted to transfer the texture. By Col to Tex.
The problem: it transmits only the Polypainting. But not the material to the texture?
Is this somehow possibly to bring the material to the texture?
