A liquid applied photoresist composition is disclosed which exhibits a favorable balance of photospeed and overall physical properties. The photoresist composition includes a binder, a multifunctional monomer, a photoinitiator, and a solvent. The photoinitiator is present in the photoresist in an amount of greater than about 10% by weight of the photoresist without solvent. The photoresist when applied is relatively resistant to blocking when applied to a substrate. A process for producing a negative resist image on a surface using the photoresist is also disclosed.
