Abstract: The present application discloses a color resist material, a filter, and a preparation method thereof. The color resist material is a trimer structure formed by polymerizing phthalocyanine dyes, wherein groups with double bonds are introduced on the phthalocyanine dyes to construct a three-molecule complex by a complexing agent, and the phthalocyanine dyes are connected by the double bonds to form a trimer structure. The color resist material with the trimer structure is stably stored in a photoresist liquid and has excellent solvent resistance, while maintains good solubility. Accordingly, a filter made of the color resist material has high transmittance and good optical performance.
