摘要: This invention relates to color-changing styryl-like compounds and the preparing of the same. A compound according to the present invention has, as its principal ring, an indoline ring of 2nd position, and has, at stimulation reversible or irreversible change(s) between a closed ring structure of a non-plane molecular structure indicated by the following chemical formula(1) showing white or pale color, and an open ring structure of a plane molecular structure indicated by the following chemical formula(2) showing vivid visible color: ##STR1## wherein Q, R.sub.1, R.sub.2, R.sub.3, Y, Z, A and X are defined in the detailed specification.
