    摘要： The present invention relates to a novel chromene compound having favorable photochromic properties, developing a color of a high density, exhibiting a small degree of initial color and permitting the color to quickly fade. The novel chromene compound has an amino group that may be substituted for a sixth position of a naphthopiran ring, has electron-donating groups at para-positions of the two phenyl groups bonded to the third position, and has at least one or more electron-attracting groups at meta-positions of the phenyl groups, and is represented, for example, by the following formula, ##STR1##
