| titleOfInvention | Photoimageable compositions |
| abstract | A negative acting photoimageable composition comprises A) between about 30 and about 70 wt%, based on total weight of A) plus B), of organic binder polymers having sufficient acid functionality to render said photoimageable composition developable in alkaline aqueous solution, A) comprising between about 3 and about 65 wt% relative to total of A) plus B) of a binder polymer A') having a weight average molecular weight between about 5000 and about 40,000 and a T g of between about 40 and about 100, and 5 to 67 wt% relative to total of A) plus B) of a binder polymer A") having a weight average molecular weight between about 41,000 and about 200,000 and a T g of between about 40 and about 100, B) between about 30 and about 60 wt%, based on total weight of A) plus B), of .alpha.,.beta.-ethylenically unsaturated compounds, said component B) comprising B') an isocyanate trimer having tri-.alpha.,.beta.-ethylenically unsaturated functionality, said trimer B') being present at between about 2 to about 30 wt % based on total weight of A) plus B), and B") 0 to about 5 wt% based on total weight of A) plus B) 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) between about 0.5 and about 15 wt %, based on total weight of A) plus B) of a photoinitiator chemical system, said photoinitiator chemical system C) comprising between about .005 and about 3 wt% relative to total weight of A) plus B) of triphenylphosphine and between about .005 and about 2 wt% relative to total weight of A) plus B) of n-phenylglycine. |
