1. Photosensitive Coating for PS Plates:

As the core photosensitizer for PS plates (pre-coated photosensitive plates), it undergoes a photodegradation reaction upon UV light exposure, generating products soluble in alkaline developers. This enables the precise transfer of patterns onto the plate, adapting to offset printing and other printing processes, and improving plate-making accuracy and printing quality.

2. Photoresist:

Used in the preparation of positive photoresists, it is applied to the fine pattern fabrication of electronic devices such as printed circuit boards (PCBs) and liquid crystal displays (LCDs). After photolithography and development, it forms high-precision etch-resistant patterns, facilitating the etching and deposition processes of electronic components.

3. Intermediate for Photosensitive Material Synthesis:

As a key intermediate, it is used to synthesize other naphthoquinone diazide photosensitizers, such as reacting with polyols to prepare high-molecular-weight photosensitive resins, used in the preparation of functional materials such as photoimaging films and photosensitive coatings.

4. Functional Polymer Modification:

Through the reactivity of the sulfonyl chloride group, it is used to photosensitively modify polymers, preparing polymer materials with photoresponsive properties. This is suitable for applications in electronic packaging, precision coatings, and other fields, improving the photochemical processing performance of the materials.

5. Fine Chemical Synthesis:

Used in the synthesis of special dyes, pigments, and photosensitive additives, its molecular structure contains diazo and sulfonyl chloride groups that can participate in various organic reactions, providing a basis for the preparation of complex functional compounds.

6. Research and Customized Photosensitive Applications:

Used as a model compound in photochemical mechanism research and for testing the performance of photosensitive materials, it can also be customized for niche applications based on specific needs, such as photosensitive coatings for miniature sensors.
