The invention discloses a light sensitization composition using a sulfonyl hydrazone compound. The composition comprises a dissolving resistant/dissolving promotion agent, an alkali soluble line type phenolic resin, an infrared absorption dye, a background dye and a solvent, wherein the dissolving resistant/dissolving promotion agent is a cyclohexanone sulfonyl hydrazone compound. The sulfonyl hydrazone compound provided by the invention is added into the light sensitization composition and can be quickly subjected to chemolysis to generate N2 for foaming only when the temperature of a scanning area is higher than 170 DEG C. In the decomposition foaming process, the membranous layer of the scanning area is loosened and is easy to develop, and most of small segments remained on the membranous layer after the decomposition are acidic materials of different types, so that an obvious dissolving promotion effect is generated during alkali development, and the composition has high thermal stability and long service life. Therefore, the cyclohexanone sulfonyl hydrazone compound is used as the dissolving resistant/dissolving promotion agent of the light sensitization composition, so that a thermosensitive computer to plate (CTP) board with high sensitivity and high development speed can be obtained.
