A polymer matrix comprising active chromophoric groups and aromatic compounds selected from phenyls substituted with one or more substituents independently selected from: (i) halogens; (ii) C<SUB>1-4</SUB>alkyl esters of carboxylic acid or their amides; (iii) -OR, -SR or -C(-O)R, R being an C<SUB>1-6</SUB>alkyl group; (iv) the group -O-(CH<SUB>2</SUB>)<SUB>n</SUB>-O-C(-O)C(X)-CH<SUB>2 </SUB>where X is CH<SUB>3 </SUB>or H and n is independently 1-6; or (v) the group -O-C(-O)C(X)-CH<SUB>2</SUB>. There is further provided a 3-dimensional optical data storage comprising a photochromic medium, where such a combination facilitates the writing of data in the 3-dimensional optical data storage. |
