Morphology

substantive + dye

The ordinary adjective 'substantive' (meaning important or significant) does not convey the technical chemistry sense of 'having natural affinity for fibres', so a B1 learner who knows the constituent words would likely interpret 'substantive dye' as an 'important dye' rather than a dye that bonds to cellulose without a mordant. This specialised, discipline-specific meaning is not predictable from the parts and therefore opaque to general learners.

Etymology

Substantive dye may come from the idea that the word substantive means having its own 'substance', so the dye can stick to cloth by itself. That's why the term means 'a dye that attaches to fibers without a mordant'.
