Abstract
A self-contained photohardenable imaging assembly comprising a first transparent polymeric film support, an imaging layer comprising a plurality of photosensitive microcapsules, a developer material and an adhesion promoter, and a second support which may be transparent or opaque is disclosed. Upon image-wise exposure and image development, an image forms in the imaging layer sealed between the supports to form an integral unit having improved peel strength.
Claims18
A self-contained photohardenable imaging assembly comprising:
- a first transparent polymeric film support, an imaging layer comprising a plurality of photosensitive microcapsules, a developer material and an adhesion promoter, and a second support which may be transparent or opaque, wherein said adhesion promoter is selected from the group consisting of bis-benzoxazoles, phenylcoumarins, bis-(styryl)biphenyls and triazinyl derivatives of diaminostilbenedisulphonic acids and mixtures thereof.
A self-contained photohardenable imaging assembly comprising:
- first and second transparent polymeric film supports, an opaque support, and an imaging layer disposed between said first and second transparent supports on each side of said opaque support, each of said imaging layers including a plurality of photosensitive microcapsules containing a chromogenic material and a developer material, at least one of said imaging layers including an adhesion promoter selected from the group consisting of bis-benzoxazoles, phenylcoumarins, bis-(styryl)biphenyls, triazinyl derivatives of diaminostilbenedisulphonic acids and mixtures thereof;
- wherein by image-wise exposing each of said imaging units to actinic radiation and subjecting the imaging assembly to pressure, images can be formed in the imaging layers on each side of said opaque support.
