  A chromene compound which contains a skeleton represented by the following formula (1) and has high color optical density at the time of exposure, double peak characteristic, little initial coloration, a practical fading speed and durability. (wherein R 1 is an electron donor group having a Hammett constant of less than 0, the ring including X is a hetero ring formed together with the 7-position and 8-position carbon atoms, and X is an oxygen atom, sulfur atom or group represented by ═NR 2 directly bonded to the 7-position carbon atom.)

  一种含有以下式子(1)所代表的骨架的香豆素化合物，在曝光时具有高色彩光密度、双峰特性、少量的初始着色、实用的褪色速度和耐久性。(其中，R1是具有小于0的Hammett常数的电子给体基团，包括X的环是与7位和8位碳原子一起形成的杂环，X是直接与7位碳原子键合的氧原子、硫原子或由═NR2表示的基团。)
