SOLUTION FOR MAKING A PHOTOCONDUCTIVE LAYER IN DRY-ELECTROPHOTOGRAPHICALLY MANUFACTURING A SCREEN OF A CRT AND METHOD FOR DRY-ELECTROPHOTOGRAPHICALLY MANUFACTURING THE SCREEN USING THE SOLUTION

摘要

Disclosed are a solution for making a photoconductive layer in dry-electrophotographically manufacturing a screen of a cathode ray tube and a method using solution. By the solution, the photoconductive layer can be stored for long time and reveals a superior photoconductivity. The solution has tetraphenyl ethylene derivatives as an electron donor material responsive to the ultraviolet rays, which has structural formula (I), in which R is H, CH3, C2H5, C3H7, OCH3, OC2H5, OC3H7, or COCH3, on a condition of excepting a case where R1=R2=R3=R4=H.
