I need expert darkroom help.

I make rubber stamps from photopolymer resin.
The first step is to produce a negative.
The industry nowadays uses a product that is contact exposed to UV
light and then washed out with a liquid developer in daylight.
It goes by various trade names, the most common being IDEAL Daylight
AQ.
I think that these people are distributors and not the actual maker.
I have had zero luck finding the actual maker of this product on the
internet.
Do anyone have any idea what this product is, and who actually makes
it? Or something similar?
Below is a link that I hope explains it all.
Best regards, thanks in advance

and here is a cut from page 4 of 8 of the link
The original stamp copy can be prepared in many different ways. The
preferred method is ...
If you are in the printing business and have a darkroom for
preparation of negatives, make the negative just as you would for any
printing job.
Otherwise, you will use the Polymer Plus Unit to produce it in
ordinary room light.
To make a negative with the Polymer Plus Unit, the original copy must
be laser printed on vellum paper.
Vellum is translucent, allowing light to pass through.
Simply insert our laser printer compatible vellum paper in the paper
tray and print!
The vellum original is placed in the Polymer Plus Unit along with a
piece of "JMP Daylight Safe Negative Film."
After exposure to ultraviolet light for about a minute and a half the
negative film is sprayed with a "water-based developer solution".
Then it is swished with a soft cotton pad and rinsed with running tap
water.
Just like that, an exceptionally high quality negative is made.
