摘要
PROBLEM TO BE SOLVED: To produce an ultraviolet-absorbing composition and an coating agent by using an ultraviolet-absorbing agent absorbable over the whole wavelength range and having high safety and stability in the environment, and provide an excellent ultraviolet-absorbing vessel produced by using the composition or the coating agent and effective for preventing the discoloration and degradation of the contents of the vessel by ultraviolet rays. ;SOLUTION: The ultraviolet-absorbing resin composition is produced by compounding a pyridazine derivative of the general formula (R1, R2, R3 and R4 are not H at the same time) or its salt as an ultraviolet-absorbing agent. A coating agent is produced by compounding the pyridazine derivative of the formula or its salt as the ultraviolet-absorbing agent and the ultraviolet- absorbing vessel produced by using the resin composition or the coating agent.;COPYRIGHT: (C)2003,JPO
