if this stuff only reflected infrared light they wouldn't be able to tell by looking at it
https://www.washingtonpost.com/archive/politics/2004/07/21/drivers-try-an-anti-photo-finish/73e1eb4a-7175-4e36-852c-0ff645a77af6/
there is a number of products that claim to do this... the main thing is that it needs to be selectively reflective for infrared light
there's other uses for such things, for example if you coat glass with a material like this, you can see through it with visible light but cameras cannot see through it
i have some safety glasses that don't look totally awful but are a very dark green colour that block IR and they dramatically reduce the visibility of my eyes, which thwarts computer visual recognition, it is the most important part, this was one of the things that was on display during the covid scamdemic, the chinese were basically bragging that they could do facial recognition automatically even when people had masks on
