Chromene compound and photochromic optical article |
| abstract |
The present invention provides a chromene compound which can exhibit excellent photochromic properties. The chromene compound of the present invention is represented by formula (1). In the formula, at least one of R1 and R2 represents a group having a radical-polymerizable group, wherein the group having a radical-polymerizable group is represented by formula (2) (wherein R10 represents a linear or branched alkylene group having 1 to 10 carbon atoms, and l represents an integer of 0 to 50); and the ring Z that is represented by formula (Z) and is spiro-bonded to a carbon atom located at position-13 in formula (1) is preferably an aliphatic cyclic group in which the number of carbon atoms that constitute the ring in conjunction with the carbon atom located at the position-13 is 3 to 20 and which may have a substituent, or the like. |
