Beschreibung
Zusammenfassung:	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.
