Abstract: The present invention relates to photoresist solution for phosphor slurry for use in the color cathode ray tube. The photoresist solution of the present invention comprises Diazo or Bisazide photosensitizer; polymer. which is mixed with said Diazo or Bisazide photosensitizer, obtained by polymerization of hydroxy ethyl acrylate base. The photoresist solution of the present invention improves the adhesive strength by using of the Diazo or Bisazide photosensitizer and the polymer, thus the green, blue and red phosphor screen being uniformly formed and the color residue being disappeared. Further, since the photosensitizer not containing heavy metal is used, it does not cause any environmental problem. Also, it can be stored for a long time by using the initiator without hydrochloric acid at the time of polymerization.
