The invention discloses a processing-free CTP plate for direct feeding-to-machine of a single coating. The CTP plate has the surface effect, the small-size effect and the quantum effect and also has high surface energy through a nano-micron styrene monomer, so that the system melting point is decreased, the coating reaches high sensitivity, thus the laser power of a plate maker can be decreased, the service life of a laser device can be prolonged, meanwhile, the phenomenon that the printing resisting rate of the coating is decreased due to the insufficient crosslinking degree is also prevented, through grafting of a hydrophobic group, the flexibility and solvent resistance of the coating can be effectively improved, cyanine dye is grafted with undecylenic acid through a molecular modification method to be modified, poor compatibility with a resin film or the separation phenomenon is prevented, the single coating formula is achieved by adding an antioxidant, the reaction of oxygen and alkaline substances in ai
