Claims
- 1. A photopolymerizable composition comprising an ethylenically unsaturated free radical polymerizable monomer, a photoinitiator for said monomer, and an aminoketone sensitizer for aqueous-developable photopolymer compositions having formula: ##STR17## wherein R.sub.1 and R.sub.2 each represent an alkyl group having 1 to 6 carbon atoms, and R.sub.3 and R.sub.4 each represent hydrogen; or at least one of R.sub.1 and R.sub.3 or R.sub.2 and R.sub.4 together represent an alkylene group having 2 to 4 carbon atoms;
- R.sub.5 represents an alkyl group having 1 to 6 carbon atoms or H;
- R.sub.6 represents an alkylene group having 1 to 16 carbon atoms;
- R.sub.7, R.sub.8, and R.sub.9 each independently represent an alkyl group having 1 to 6 carbon atoms, or any two of R.sub.7, R.sub.8, and R.sub.9 taken together represent an alkylene group having 4 to 6 carbon atoms, or R.sub.7, R.sub.8, and R.sub.9 taken together with the N atom to which they are bonded represent a quinuclidinio group, or R.sub.6 taken together with R.sub.7, R.sub.8, or R.sub.9 represent a five, six, or seven membered heterocyclic ring group, and
- X.sup.- represents any anion.
- 2. The photopolymerizable composition of claim 1 wherein R.sub.1 and R.sub.2 independently represent an alkyl group having 1 to 6 carbon atoms.
- 3. The photopolymerizable composition of claim 2 wherein R.sub.7, R.sub.8, and R.sub.9 independently represent an alkyl group having 1 to 6 carbon atoms.
- 4. An article comprising a substrate having on at least one surface thereof the photopolymerizable composition of claim 3.
- 5. An article comprising a substrate having on at least one surface thereof the photopolymerizable composition of claim 2.
- 6. The photopolymerizable composition of claim 1 wherein R.sub.7, R.sub.8, and R.sub.9 independently represent an alkyl group having 1 to 6 carbon atoms.
- 7. An article comprising a substrate having on at least one surface thereof the photopolymerizable composition of claim 6.
- 8. The photopolymerizable composition of claim 1 wherein R.sub.6, R.sub.7, R.sub.8, and R.sub.9 form an N,N-dimethylpiperidinio-4-yl group with the N.sup.+ atom to which they are attached.
- 9. An article comprising a substrate having on at least one surface thereof the photopolymerizable composition of claim 8.
- 10. An article comprising a substrate having on at least one surface thereof the photopolymerizable composition of claim 1.
- 11. The photopolymerizable composition of claim 1 wherein said monomer comprises pentaerythritol tetraacrylate, said initiator comprises diphenyliodonium hexafluorophosphate, and said sensitizer comprises 10-(3-(N-ethyl-N-(2-(N-methylpiperidinio)ethyl)-4-aminophenyl)propenoyl)-1H,2H,3H, 5H,6H,7H, 11H-[[1]benzopyrano[6,7,8-ij]quinolizin-11-one methylsulfate.
