A plate making film has a layer provided on a transparent substrate, the layer consisting essentially of a polymeric compound composed of a repeating unit represented by the following general formula (1):
where A is
x, y and z each denote an integer of 1 or more, X is a residue of an organic compound having 2 active hydrogen groups, Y is a hydrocarbon group having 1 or more carbon atoms, and R1 is a dicarboxylic acid compound residue, or a diisocyanate compound residue. On the plate making film, an image is formed, preferably, by ink jets using, preferably, a plate making ink containing a mono- or disazo dye which is a yellow dye highly ultraviolet absorbing properties for a wavelength of 350 to 450 nm. An inexpensive, high resolution, high grade photomask for plate making is produced thereby.
一种制版薄膜在透明基底上有一层,该层主要由由下式(1)表示的重复单元组成的高分子化合物构成:
其中 A 是
x、y 和 z 分别表示 1 或 1 以上的整数,X 是具有 2 个活性氢基的有机化合物残基,Y 是具有 1 个或 1 个以上碳原子的烃基,R1 是二
羧酸化合物残基或二
异氰酸酯化合物残基。在制版薄膜上,最好通过喷墨形成图像,喷墨最好使用含有单偶氮或二偶氮
染料的制版墨
水,这种
染料是一种对 350 至 450 纳米波长的紫外线具有高度吸收特性的黄色
染料。这样就能制作出廉价、高分辨率、高等级的制版用光罩。
