Some novel amino-substituted spiroindolinonaphthopyrans have been synthesised. Whilst these compounds exhibit no observable photochromic properties at ambient temperature, protonation results in ring opening to give stable, intensely coloured dyes. Recyclisation and decolouration result on basification.
