WIPO Patent Application WO/2016/031738
Kind Code:
A1
Abstract:
[Problem] To provide a tube which can effectively protect a fluid inside the tube from the influences of ultraviolet rays and through which the fluid can be viewed from outside.
[Solution] A tube comprising an ultraviolet-shielding layer formed from a resin composition which contains, dispersed therein, a yellow organic pigment and an ultraviolet absorber comprising an inorganic compound. The organic pigment and the ultraviolet absorber in the resin composition have been dispersed so that the concentrations thereof each have a standard deviation (σ) of 0.02% or less. The tube has a light transmittance at wavelength 350 nm of 4-14% and a light transmittance at wavelength 400 nm of 5-19%, in terms of the light transmittance of a 10-fold diluted film of the same thickness.
