Infra-red absorbing polymers useful in imageable products and the lithographic printing field comprise infra-red absorbing groups carried as pendent groups on a polymer backbone. Certain infra-red absorbing groups may also act to insolublize the polymer in a developer, until it is imagewise exposed to infra-red radiation. The resulting heat renders the polymer soluble in the developer. Imageable products employing the infra-red absorbing polymers may include positive working lithographic printing plates.
可用于成像产品和平版印刷领域的红外线吸收聚合物由聚合物主链上作为悬垂基 团的红外线吸收基团组成。某些红外线吸收基团还可以使聚合物在显影剂中不溶解,直到它被红外线辐射成像。由此产生的热量可使聚合物溶于显影剂中。使用红外线吸收聚合物的可成像产品可包括正片平版印刷板。
