What material is used to make luminescent placard on civil aircraft? [closed]

I'm an engineer working in the civil aviation industry. Currently my company is preparing to make some placards. I've downloaded the drawings from Airbus. A drawing calls up the material of AD400 TV25/3881/83. I've seen the original OEM placard and I remember it's luminescent (it's located next to the emergency door).

I've searched "AD400" and "TV25/3881/83" as the keyword on Google but found nothing useful. I think it might be the spec of the material, but what it really is and where I can get it.

It will be greatly appreciated if someone can tell me more info on this material. It would be much better if someone can tell me where I can buy this material.

Update: Below is how the placard looks like (a screenshot taken from the drawing):

The diamond 12 calls up the material of AD400 TV25/3881/83. Also the drawing says the base material is " MAKROFOL-E". I know "MAKROFOL" is a kind of PC film and it's a trademark of Bayer, but I didn't find this material on the website of Bayer either.

• You appear to be asking what materials you should use to manufacture a piece of safety equipment. You absolutely must not rely on answers from random people on the internet for a safety critical system. Ask Airbus, not us. May 21 '15 at 19:20

I don't know what exactly AD400 TV25/3881/83 is, but if you are talking about a sign like this:

It appears to be plastic and Larchfield sells them. This material AD400 TV25/3881/83 could very well be a type of plastic, but I don't know about it.

In my opinion, you can contact companies which make or sell them (Larchfield or this or this) to get more reliable information.
