The coloration reaction of some spirochromenes (SP) has been investigated in the case of a free radical photosensitive system composed of a poly(N-vinylcarbazole) matrix (PVCz) in dichloromethane containing carbon tetrachloride as an activator at average ratios of 5:1:0.1 for PVCz, CCl4 and SP, respectively
