The present invention relates to an optical stabilizer having excellent weather resistance, a method for producing the same, and a use thereof, and more particularly, to 2,2,6,6-tetramethylpiperidine, having excellent compatibility with various resins and paints. The present invention relates to a urea-based light stabilizer, a preparation method thereof, and a use thereof. Urea-based light stabilizers incorporating 2,2,6,6-tetramethylpiperidine according to the present invention are excellent in weatherability, excellent in light stability compared to conventional light stabilizers, and manufactured in an economic process. This shortening can be expected to reduce manufacturing costs and improve productivity. |
