摘要：
A compound, 3-phenyl-7-[4-(tetrahydrofurfuryloxy)phenyl]-1,5-dioxa-s-indacene-2,6-dione, which has a structure of crystals exhibiting the strongest peak at an angle of diffraction, 2ϑ , of 4.7°, among peaks appearing within the range of not smaller than 3° of 2ϑ , in an X-ray diffraction using a Cu-Kα -ray. The compound gives dyed or printed products having deep and brilliant tint of colors with excellent fastnesses, when applied to hydrophobic fiber materials, particularly, polyester fiber materials.
