| 摘要 |
The invention relates to the colouration of high molecular weight organic materials in the mass with soluble phthalocyanine precursors of structure <IMG> or isomers thereof, to the soluble phthalocyanine precursors as such wherein M is Zn, Ti or V or wherein L, is morpholino, pyrrolidino or with C1-C12alkyl substituted piperidino, to compositions containing high molecular weight organic materials and the above soluble phthalocyanine precursors, and to a process for making structured colour images and applications thereof.
