    摘要: A chromene compound having a skeleton represented by the following formula (1) and exhibiting double peak characteristic: wherein Z is a group represented by any one of the following formulas: n is an integer of 1 to 3, when n is 2 or 3, Z′ s may be the same or different, with the proviso that when n is 1, Z cannot be —CH2—, and when n is 2 or 3, Z's cannot be —CH2— at the same time; R1 is an electron absorbing group having a Hammett constant σp of more than 0, with the proviso that when there are a plurality of R1's, R1's may be the same or different; and X and Y are each independently an oxygen atom or ═NR2, with the proviso that X and Y cannot be oxygen atoms at the same time.
