I have been involved with DYLUX at Du Pont for over thirty years and am a
friend of Tom Gravell who pioneered the idea of using a photosensitve paper
(which does not require processing) to record watermarks.  In the event that
no one else floods you with information, let me know, and I shall try (1) to
send you a draft I am writing about this, (2) try to get some DYLUX paper for
you.  DYLUX 503 is sold by printing supply dealers who sell Du Pont products
all over the world, and there surely is some that can be located in UK.  

Let me know if I can help.
