阳图热敏CTP版材用感光组成物及使用其制作的平印版
摘要：
本发明公开了一种感光组成物和使用感光组成物制作的平印版，感光组成物包含下列组分，按重量份计，碱树脂的用量占组成物固体总量的30－60份，红外吸收化合物用量占组成物固体总量的5－20份，光热产酸源用量占组成物固体总量的5－20份，酸解阻溶化合物占用量占组成物固体总量的5－15份，发生物理变化的阻溶化合物占用量占组成物固体总量的5－15份。平印版包含底基，在底基上是含亲水性聚合物的底涂层，在底涂层附着有前述感光组成物的光敏涂层。本发明由于采用上述组分，样品通过多个印版的实验得出印版影像印程可达10万印次，该版如在220℃中烤10分钟，印程可达30万印次，具有感度高、显影宽容度大的优点。
摘要（英）：

The invention discloses a sensitizing composition and a lithograph plate using the sensitizing composition. The sensitizing composition comprises the following components by weight portion according to solid amount of the composition: 30 to 60 portions of alkali resin, 5 to 20 portions of infrared absorption compound, 5 to 20 portions of photo-thermal generating-acid source, 5 to 15 portions of acidolysis dissolution resistant compound, and 5 to 15 portions of physically changed dissolution resistant compound. The lithograph plate comprises a base, the base is provided with a bottom coating containing hydrophilic polymers, and a light-sensitive coating of the sensitizing composition is adhered to the bottom coating. Because the sensitizing composition and the lithograph plate adopt the components, by testing a plurality of printing plates, the image printing number of the printing plate reaches 100,000; if the lithograph plate is roasted at a temperature of 220 DEG C for 10 minutes, the printing number can reach 300,000; moreover, the lithograph plate also has the advantages of high sensitivity and large development latitude.
