Non-tacky photoimageable electrodepositable photoresist composition |
摘要 |
An electrodepositable photoresist composition comprising an aqueous dispersion of: (a) a water-dispersible neutralized cationic polymeric material having a pendant unsaturation, (b) a nonionic unsaturated material and (c) a photoinitiator; characterized in that it can form smooth, thin and pinhole free coatings and further characterized in that the film is capable of being selectively insolubilized by patterned radiation exposure such that the unexposed portion of the film is soluble in dilute aqueous acid and the exposed portion is insoluble in said aqueous acid.
