Preparation method of photosensitive resin

① Make the polymer compound itself have a photosensitive functional group, such as polyvinyl alcohol laurate, which generates an intermolecular cross-linking reaction under light: After solvent treatment, a relief image can be made.

② Add a photosensitive compound to the polymer compound and react with the polymer compound under light, such as adding dichromate to gelatin or polyvinyl alcohol, and diazo compounds to cyclized rubber. 

③ It is made by photopolymerization of olefinic monomer with photopolymerization ability.
