Is the Polypropylene safe to use on car paint?

We have a DesignJet Z2100 and use HP Everyday Gloss Polypropylene (C0F28A) in it.

We get great results, and combined with a decent laminate it has survived on the exterior of the window of my car for 6 weeks now with no fading.

Just wondering if the Adhesive is suitable for use on car paint? I can't find any information on the adhesive apart from it being permanent.
