摘要: Multilayer, positive working, thermally imageable elements are disclosed. The elements produce bakeable lithographic printing plates that are resistant to press chemistries. The elements have a substrate, an underlayer, and a top layer. The underlayer comprises a resin or resins having activated methylol and/or activated alkylated methylol groups, such as a resole resin, and a polymeric material that comprises, in polymerized form, (a) methacrylic acid; (b) N-phenylmaleimide, N- cyclohexylmaleimide, N-benzylmaleimide, or a mixture thereof; and (c) one or more monomers of the structure:
in which:
R 1 is H or methyl; X is -(CH 2 ) n - , where n is an integer from 2 to 12; -(CH 2 -CH 2 -O) p -CH 2 -CH 2 -, where p is an integer from 1 to 3; or -Si(R')(R")-where R' and R" are each independently methyl or ethyl; and m is 1, 2, or 3.摘要翻译: 公开了多层,正面加工,可热成像的元件。 这些元件产生耐压印化学品的可烘烤平版印刷版。 元件具有基底,底层和顶层。 底层包括具有活化的羟甲基和/或活化的烷基化羟甲基的树脂或树脂,例如甲阶酚醛树脂和聚合物形式的聚合物,所述聚合物包含(a)甲基丙烯酸; (b)N-苯基马来酰亚胺,N-环己基马来酰亚胺,N-苄基马来酰亚胺或其混合物; 和(c)一种或多种结构单体:其中:R 1是H或甲基; X为 - (CH 2)n - ,其中n为2至12的整数; - (CH 2 -CH 2 -O)p -CH 2 -CH 2 - ,其中p是1至3的整数; 或-Si(R')(R“) - 其中R'和R”各自独立地为甲基或乙基; m为1,2或3。
