It is imaged coating, thermosensitive negative planographic printing plate and its method for platemaking the invention discloses a kind of this can be imaged the component that coating includes following mass fraction：20 60 parts of polymerizable compound, 0.5 12 parts of radiation absorbing compound, 1 25 parts of radical initiator, 10 70 parts of binding agent, 0.5 15 parts of development accelerant.Method for platemaking includes the following steps：S1, plate precursor is prepared, the plate precursor includes with water-wetted surface or be endowed the base of hydrophilic layer and be covered on the base to be imaged coating；Plate precursor described in S2, patterned exposure, so as to form exposure area and unexposed area；S3, the unexposed area is removed by developing procedure.Using it is above-mentioned be imaged coating and method for platemaking can realize " developing in machine " or " development of disembarking " flexible developing procedure and galley obtained with excellent printing performance. |
