(A) 인쇄판으로써 인쇄하는 동안 사용된 친유성 잉크 및 알칼리성 또는 산성의 수성 습수액, 및 (B) 인쇄판의 현상 동안 사용된 알칼리성 또는 산성의 수성 현상액에 접근가능 및 불용성인 접착층을 포함하는 적층된 평판 인쇄판. 이러한 접착층이 또한 (I) 상기 현상액 및 상기 습수액이 산성일 때, 알칼리성 수성 처리액에 가용성이고, (II) 상기 현상액 및 상기 습수액이 알칼리성일 때, 산성 수성 처리액에 가용성이고, (III)가융성이고, 또는 (IV) 60 쇼어-A 이하의 경도를 가지는 건조 접착성 유연층이다. 따라서 이러한 접착층은 인쇄판의 박리를 가능하게 한다. A laminated lithographic printing plate comprising an adhesive layer that is accessible to and insoluble in (A) oleophilic inks and alkaline or acidic aqueous fountain solutions used during printing with the printing plate, and (B) alkaline or acidic aqueous developers used during development of the printing plate. This adhesive layer is also (I) soluble in an alkaline aqueous processing liquid, when said developers and said fountain solutions are acidic, (II) soluble in an acidic aqueous processing liquid, when said developers and said fountain solutions are alkaline, (III) meltable, or (IV) a dry adhesive compliant layer having a hardness of 60 Shore-A or less. This adhesive layer thus allows delamination of the printing plate.
