Chromene compounds |
| abstract |
Chromene compounds having structures which are represented by the general formula (1): (1) (wherein R1 to R4 are each hydrogen, alkyl, aryl, or the like with the proviso that at least two of R1 to R4 must not be hydrogen; R5 to R8 are each alkyl, aryl, or the like; m and n are each an integer of 0 to 4; and x and y are each an integer of 0 to 5) and in which a six-membered ring having specific substituents is fused to a 2H-benzo[h]chromene skeleton with the 5- and 6-position carbon atoms of the skeleton held in common. The chromene compounds have advantages in that they emit yellow or middle colors by themselves and that their photochromic characteristics do not deteriorate even when the compounds are used together with photopolymerization initiators. |
