Thanks Sam and Tim, and also to Gregjohn for his original question

I found out about interior_texture a little while ago by reading and
experiments

I found that I had to use keyword uv_mapping or the text was pixelated as
before

For anyone else, here is an example of a disc with text and background on
one side and background only on the other side


#declare my_text= text{   ttf"arialbd.ttf"      "This is a test"    1,0

  translate -z/2
// suggested by fellow pover Samuel Benge  Date: 21 Oct 2007 20:39:07
// Re: Simple 2D text on a cylinder's surface
  scale .2
  //rotate <0,0,90>
  translate<-.7,0,0>
   // when the Z rotation is 90, then these parameters are y,x,z
   // when the Z rotation is 0, then these parameters are x,y,z
}

disc {
  <0, 0, 0>  // center position
  y,         // normal vector
  1.0,       // outer radius

    uv_mapping
      texture {                     // one side has background and text
      pigment{
        pigment_pattern{
          object{my_text 0,1}
          }
        pigment_map{
            [0 color Black]
            [1 color White]
        }
      }
    }
    interior_texture {             // the other side has another background
      pigment {
            color Blue
        }
      }
    rotate x*-45
    rotate x*90*clock             // look at both sides of the disc
}
