求翻译：主要原因：一是国内配套中间体尚不成熟，例如缩合型偶氮颜料、异吲哚啉酮和异吲哚啉类颜料合成中所需的中间体缺乏；二是颜料化关键技术尚不过关，研发尚需时日。是什么意思？

Main reasons: First, is not yet mature domestic supporting intermediate, such as condensed azo pigments, different indoline ketone and iso-indoline class of pigment synthesis in the absence of the necessary intermediates; second, pigment-based technology is not yet pass key R & D will take some

The main reasons are: 1) Domestic supporting intermediates is not yet mature, such as condensation type azo pigments, different indole 1,3,3 1,3,3 indole-3 -methadone and different types of pigment synthesis intermediates required; 2 lack of pigment is still substandard key technologies, research an

Main reasons: one is the domestic supporting intermediates are immature, condensation azo pigments, such as the different effects of indole derivatives and indole complexes of such intermediates for pigment synthesis you want in the lack of second pigment of key technology does not cross the border,
