## Abstract The reaction of PVA with 2,2‐dialkoxyethoxystyrylpyridinium or quinolinium salts is described. The resultant water‐soluble polymers, which contain small amounts of the styrylpyridinium‐ or quinolinium group, exhibited high photosensitivity. Among the polymers prepared PVA‐bearing 4‐oxys
