The photochemical sensitizing treatments of PVK were studied with respect to the solution system. The standard solution contained carbon tetrabromide, N-vinylcarbazole, PVK and benzene. To account for the some behaviors of the photochemical reaction, we observed IR spectra, elementary analysis, viscosity, gel-permiation chromatogram and gas chromatogram. And also, we had tried the investigation of blue dye formation process using N-vinylcarbazole substituents and PVK derivatives. We could confirm the crosslinkage of PVK, carbazole formation from N-vinylcarbazole and presumed the formation of blue dye component similar to 3, 3'-carbazolylmethane dye. We could observe the direct interaction between blue dye formation and NVK in the standard solution.
