The Effects of Irradiation Dose and of Photopolymer Composition on the Dissolution of Entrapped Dyes.

Dissolution kinetics of dyes entrapped in photocrosslinked polymer matrix were investigated. Films containing thymine‐based bioinspired photopolymers and non‐toxic dyes were deposited on the polyethylterephthalate (PET) substrate from aqueous solutions. The films were cured by exposure to various UV‐irradiation doses (λ=254 nm) and developed in a weakly acidic aqueous medium. The UV‐Vis spectra of the films before and after curing and development were taken and the intensities of the bands corresponding to the absorbance of the respective dyes entrapped in the films were monitored for a variety of irradiation doses, development times, polymer compositions and two different dyes.
