Bromophenol blue (R) (BPB) dyed with the rosin and isopropyl alcohol produc
es a him with a uniform yellow appearance, which can be deposited on glass
plates by simple technique. This mixture shows good photosensitivity in the
blue light (lambda = 457 nm line) employing argon-ion laser and presents h
igh resolution for holographic application. Consequently, it is possible to
obtain holographic elements, e.g., gratings. (C) 2001 Published by Elsevie
