摘要： Novel imidomethyl or amidomethyl derivatives of 1,3,3trimethylindolino-spiropyran are produced by reacting a 1,3,3trimethylindolino-spiropyran derivative with an imidomethylating or amidomethylating agent in the presence of a condensing agent and optionally in a solvent. These novel compounds are adapted to be used as a coloring matter for pressure sensitive copy papers and particularly as one component of a coloring matter for black pressure sensitive copy papers.
