<p>Disclosed is a method for producing a relief printing plate wherein dust produced on the printing plate during the engraving can be easily removed. Also disclosed is a rinsing liquid for the production of a relief printing plate, which is suitable for use in the method for producing a relief printing plate. The method for producing a relief printing plate is characterized by comprising, in the following order, a step of preparing a relief printing original plate that has a relief-forming layer, a step of engraving the relief printing original plate by exposure to light, and a step of removing the engraving dust with a rinsing liquid, said dust being produced by the engraving. The method for producing a relief printing plate is also characterized in that the rinsing liquid is an aqueous solution having a pH of 9 or more, and the relief-forming layer contains a polymer that has a group represented by the following formula (I). -M(OR1)(R2)n (I) (In the formula, R1 represents a hydrogen atom or a hydrocarbon group; M represents Si, Ti or Al; when M is Si, n is 2; when M is Ti, n is 2; when M is Al, n is 1; n-number of R2s each independently represents a hydrocarbon group or OR3; and R3 represents a hydrogen atom or a hydrocarbon group.)</p> |
