摘要：
In various embodiments, a recording medium comprises an oleophilic substrate and, thereover, a topmost oleophobic layer comprising a cured polymeric silicone matrix that consists essentially of the addition-cure reaction product of a vinyl-functional polydialkylsiloxane and a silane cross-linking agent. The vinyl-functional polydialkylsiloxane has a molecular weight ranging from 30,000 to 75,000 or 1 10,000 to 130,000. If the molecular weight of the vinyl-functional polydialkylsiloxane is within the range of 30,000 to 75,000, the molar ratio of silane groups to vinyl groups is within the range of about 11 :1 to about 25:1; and if the molecular weight of the vinyl-functional polydialkylsiloxane is within the range of 110,000 to 130,000, the molar ratio of silane groups to vinyl groups is from about 5:1 to about 27:1. The recording medium may be used as a lithographic printing plate.
摘要（中）：
在各种实施方案中，记录介质包括亲油性底物，并且其中最外层的疏油层包含固化聚合物硅氧烷基质，其基本上由乙烯基官能聚二烷基硅氧烷和硅烷交联剂的加成固化反应产物组成。 乙烯基官能聚二烷基硅氧烷的分子量范围为30,000至75,000或11000至130,000。 如果乙烯基官能聚二烷基硅氧烷的分子量在30,000至75,000的范围内，则硅烷基与乙烯基的摩尔比在约11:1至约25:1的范围内; 并且如果乙烯基官能聚二烷基硅氧烷的分子量在11万至13万的范围内，则硅烷基与乙烯基的摩尔比为约5:1至约27:1。 记录介质可以用作平版印刷版。
