A photoimageable composition of the negative acting type which includes a binder polymer which contains carboxyl groups is provided with a metal chelate in which the coordination number of the metal is 2 or higher. When the photoimageable composition is coated as a layer on a dry film, the metal chelate reacts with the carboxyl groups of the polymer, releasing a metal ion which bridges carboxyl groups of two or more polymer molecules. This bridging reduces cold flow of the photoimageable composition layer of the dry film.
