적어도 SiH기 함유 화합물과, 하기 일반식 (I)로 나타내어지는 화합물과, 하기 일반식 (II)로 나타내어지는 화합물 및/또는 하기 일반식 (III)으로 나타내어는 화합물을 포함하는 인쇄판용 실리콘 조성물로서, 상기 일반식 (I)로 나타내어지는 화합물의 D, 상기 일반식 (II)로 나타내어지는 화합물의 G 및 상기 일반식 (III)으로 나타내어는 화합물의 J가, 아세톡시기 및/또는 디알킬옥시미노기인 인쇄판용 실리콘 조성물. A-Si-(D)(I) (일반식 (I) 중, A는 SiH기와 히드로시릴화 반응하는 비가수분해성의 관능기를 나타낸다.) E-Si-(G)(II) (일반식 (II) 중, E는 SiH기와 히드로시릴화 반응하지 않는 비가수분해성의 관능기를 나타낸다.) Si-(J)(III) 고속 경화형의 실리콘 고무층이면서 하층과의 접착성에도 뛰어나고, 또한 잉크 반발성이나 내상처성에도 뛰어난 평판 인쇄판 원판 또는 평판 인쇄판을 얻기 위한 인쇄판용 실리콘 조성물을 제공하는 것. The present invention provides a silicone composition for use in a printing plate, the composition including at least: a SiH group-containing compound; a compound represented by the following general formula (I); a compound represented by the following general formula (II); and/or a compound represented by the following general formula (III); wherein Ds in the compound represented by the general formula (I), Gs in the compound represented by the general formula (II) and Js in the compound represented by the general formula (III) each represents an acetoxy group or a dialkyloximino group: A-Si-(D) 3 (I) (wherein in the general formula (I), A represents a non-hydrolyzable functional group capable of undergoing a hydrosilylation reaction with a SiH group); E-Si-(G) 3 (II) (wherein in the general formula (II), E represents a non-hydrolyzable functional group incapable of undergoing a hydrosilylation reaction with a SiH group); and Si-(J) 4 (III). An object of the present invention is to provide a silicone composition for use in a printing plate, for obtaining a planographic printing plate precursor or a planographic printing plate which includes a silicone rubber layer having an excellent adhesion to an underlying layer despite being a fast-curing silicone rubber layer, and which has an excellent ink repellency and scratch resistance.
