Preliminary results are presented on the spectroscopic properties and photocross-linking behaviour of a novel water-soluble poly(vinyl alcohol) modified with pendant styrylthiazolium groups and are compared with those of the model chromophore, (E)-2-

Poly(vinyl alcohol) modified with 2-p-(formylstyryl)-3,4-dimethylthiazol-3-ium shows a very high photosensitivity even when substitution levels are only 1–2 mol%. The trans structure of the model chromophore has been confirmed by FT NMR. Upon expos
