They were not considered laserable by Romark because they did tend to curl a bit especially when large parts were cut out, like a picture.
They said that the material had no PVC and could be used in a laser safely, as all of their materials.
I have not tried their yellow, but the blue and red are the toughest to laser. The color does not change and disappear when engraved. It will redeposit on the item in the direction of the airflow.
The trick around this is to either engrave it with a much lower power a second time, or use a stiff brush and some lighter fluid to remove the colored powder deposit. Usually doing both gets a faintly better result. Looking critically at the white behind the blue, there will be a faint blueness there, but against the blue it is quite white. [Maybe that faint blueness will disappear after 15 years.]
