苯并吡喃着色剂及其制备方法和使用方法
摘要：
式(I)的化合物，式中X为氢或式(II)的基团，R1每次出现时独立地为C1－C20脂族基团，C3－C10脂环族基团，或者C3－C10芳族基团；R2，R3，R4和R5每次出现时各自独立地为卤素，硝基，氰基，羟基，C1－C20脂族基团，C3－C20脂环族基团，或者C6－C20芳族基团；以及“n”，“q”和“p”各自独立为0～3的整数，及“m”为0～4的整数。
摘要（英）：

The invention provides a compound of Formula (I) wherein X is hydrogen or a radical of Formula (II), R<1 >independently at each occurrence is a C1-C20 aliphatic radical, a C3-C10 cycloaliphatic radical, or a C3-C10 aromatic radical; R<2>, R<3>, R<4> and R<5> are independently at each occurrence a halogen, a nitro group, a cyano group, a hydroxy group, a C1-C20 aliphatic radical, a C3-C20 cycloaliphatic radical, or a C6-C20 aromatic radical; and ''n'', ''q'', and ''p'' are each independently integers having a value of 0 to 3, and ''m'' is an integer having a value of 0 to 4.
