 we are a comapny dealing with many things and now want to produce
plastic photochromatic lenses for which we 've  the dyes .
             we want to know about the following things 
1- how to use the dyes in allyl-di-gycol(CR-39) . we do't want them to
use by en-mass-capsulation except it we wish to use them . BY
IMBIBITION & COATING PROCESS
2- We want to know each and every technical detail for those
process(IMBIBITION & COATING)
3-   we want to know that by which chemical's & method  and process 
we"ll be able to  do that
4-   we want to know on  which plastics this can be done 
5-   where this chemical's/methods  are  for sale .
6-   how to got them 
7-   In these plastics water based colors are imbibed normally but non
of the organic dye show any type of imbibing . Is it possible to make
the dyes water soluble (as leuko dyes shows after treating them with
SO2 )
