| titleOfInvention | Photoimageable compositions containing photopolymerizable urethane oligomers |
| abstract | A negative acting photoimageable composition comprises: (A) 30 to 70 wt.% of organic binder polymers having sufficient acid functionality to render said photoimageable composition developable in alkaline aqueous solution and comprising: A') 3 to 65 wt.% of a binder polymer having a weight average molecular weight of 5000 to 40,000 and a Tg of 40 to 100 DEG C, and A") 5 to 67 wt.% of a binder polymer having a weight average molecular weight of 41,000 to 200,000 and a Tg of 40 to 100 DEG C, (B) 30 to 60 wt.% of alpha , beta -ethylenically unsaturated compounds comprising: B') an isocyanate trimer having tri- alpha , beta -ethylenically unsaturated functionality, said trimer being present at from 2 to 30 wt.%, and B") 0 to 5 wt.% of other alpha , beta -ethylenically unsaturated compounds, at least about 50 mole percent of the alpha , beta -ethylenically unsaturated functionality of (B') and (B") being methacrylate functionality and (C) from 0.5 to 15 wt.% of an organic, radiation-sensitive free-radical generating photoinitiator chemical system, comprising from 0.005 to 3 wt.% of triphenylphosphine and from 0.005 to 2 wt.% of n-phenylglycine, all said percentages being based on the total weight of (A) plus (B). |
