Claim 0:
1. A polymerizable composition, which comprises:
at least one polythiol compound;
at least one polyisocyanate compound; and
at least two ultraviolet absorbers;
wherein the at least two ultraviolet absorbers comprise at least one first ultraviolet absorber having a primary absorption wavelength (λ1) in a wavelength range of 320 nm to 350 nm; and
at least one second ultraviolet absorber having a primary absorption wavelength (λ1′) in a wavelength range of 250 nm to 300 nm,
wherein the first ultraviolet absorber further has another primary absorption wavelength (λ2) in a wavelength range of 290 nm to less than 320 nm, and the second ultraviolet absorber further has another primary absorption wavelength (λ2′) in a wavelength range of 320 nm to 350 nm.
