| titleOfInvention | Amino-functional photopolymer compositions and photo-oxidation imaging processes employing same |
| abstract | The present invention relates to amino-functional photopolymer compositions and to photo-oxidation imaging processes utilizing such compositions. The amino-functional photopolymer compositions comprise amino-functional polymers and photosensitizing agents which, when exposed to electromagnetic radiation in the presence of ordinary molecular oxygen, are cured, thereby forming a less soluble polymer. Where the irradiation has been done selectively or in an imagewise fashion, the compositions allow for the development of an image by virtue of the solubility or redispersibility differential between the exposed and unexposed portions of the compositions. The amino-functional photopolymer may be any of a large variety of types, but generally will comprise a polymer with two or more amino-functional groups. The polymer may be a soluble polymer or a small-particle-size microgel cross-linked polymer. The photopolymer may also comprise mixtures of soluble polymer and small-particle-size microgel cross-linked polymer. The amino-functional photopolymer may be rubbery, leathery or glassy. The photosensitizer incorporated in the amino-functional photopolymer composition may be any of a large number of photosensitizers which stimulate the production of singlet molecular oxygen; for example, tetraphenyl porphorin (TPP) and its derivatives and salts, fluoranthene, dinaphthalene, thiophene, rose bengal, etc. By varying the photosensitizer used in the compositions, the amino-functional photopolymer composition in the presence of ordinary molecular oxygen may be made sensitive to photo-curing by ultraviolet or visible irradiation, including green light and red light. The compositions may contain other constituents in addition to the amino-functional polymer and photosensitizer. For example, other polymers or resins without amino-functionality may be incorporated to aid in adapting the compositions for use in particular applications as are discussed herein. |
