6. The ultraviolet-curable resin composition according to claim 1, characterized in that: the initiator is hydroxy cyclohexyl phenyl ketone, the catalyst is cuprous tert-butyl alcohol, the antioxidant is hydroquinone, and the polymerization inhibitor is p-tert-butyl catechol.
7. A color film prepared from the ultraviolet curable resin composition of any one of claims 1 to 6, wherein: the color film is of a multi-film structure, and the using amount of the fluorine-containing acrylic monomer in the ultraviolet curing resin composition is reduced layer by layer from one side film layer to the other side of the color film.
8. The color film of claim 7, wherein: the thickness of the color film is 8-20 μm; the multi-layer structure comprises 2-4 layers.
9. The color film of claim 7, wherein: when the color film is prepared, the ultraviolet curing resin composition is formed into a film and patterned through ink jet printing, coating or photoetching processes.
10. The flexible OLED packaging structure prepared by adopting the color film of any one of claims 7 to 9 is characterized in that: the flexible OLED packaging structure is an OLED/inorganic film layer/Resin/CF/inorganic film layer, wherein the Resin thickness is 0.1-5 mu m; CF is a color film, and the usage amount of fluorine-containing acrylic monomers in the film layer on the side far away from the OLED is less.
