What Is 107761-81-9 DNQ Photoactive Compound?

2,3,4,4'-Tetrahydroxybenzophenone 1,2-Naphthoquinonediazido-5-Sulfonate (CAS 107761-81-9) is a DNQ-based photoactive compound used in positive photoresist systems. As a key component in pac photoresist formulations, it contributes to exposure-induced dissolution behavior and is different from photoacid generators (PAGs) used in chemically amplified photoresists.

DNQ Photoactive Compound for Positive Photoresist Applications

CAS 107761-81-9 is used as a DNQ-based photoactive compound in positive photoresist materials formulations, where the photosensitive component works together with resin and solvent systems to control exposure-dependent dissolution behavior.

The final performance of a photoresist formulation depends on multiple factors, including the selected resin, solvent composition, photoactive compound concentration, exposure conditions and development process.

When evaluating this material, formulation teams typically consider:

Evaluation Factor	Description
Photoactive compound compatibility	Interaction with the selected resin system
Solubility behavior	Compatibility with formulation solvents
Exposure response	Performance under the intended exposure conditions
Development behavior	Dissolution difference before and after exposure
Material purity	HPLC purity and relevant impurity control
