SPECIFIC COMPOUNDS - 1 Compound i.e. 2-isobutyl-4,7-bis-(4-isopropoxy-phenyl)-2H-benzotriazole of formula (I'), is disclosed as the luminescent dye.    EXAMPLE - Synthesis of pressure sensitive adhesive wavelength conversion tape was carried out as follows. A pressure sensitive wavelength conversion layer comprising luminescent dye, and adhesive polymeric material, was fabricated onto glass plate. The pressure sensitive wavelength conversion layer was fabricated by preparing 80 wt.% poly(butyl acetate-co-acetic acid) (BA/AA) polymer solution with dissolved polymer in toluene; preparing chromophore containing BA/AA matrix by mixing BA/AA solution with synthesized chromophore comprising 2-isobutyl-4,7-bis-(4-isopropoxy-phenyl)-2H-benzotriazole at weight ratio (chromophore/ BA/AA) of 0.2 wt.% to obtain chromophore-containing adhesive polymer solution; forming chromophore/polymer film by directly casting chromophore-containing polymer solution onto B270 glass plate (2.5 cm x 2.5 cm); then heat treating plate in vacuum oven at 150 degrees C for 1 hour to remove toluene; and then two specimens were attached together and manually pressed between two glass plates with 100 mu m glass beads at 150 degrees C to obtain glass laminated with pressure sensitive wavelength conversion layer.
