感光性树脂组合物、感光性树脂层压体、树脂图案的制造方法、固化膜和显示装置
Abstract:
本发明提供感光性树脂层层压在支承薄膜上而得到的感光性树脂层压体，所述感光性树脂层包含(A)碱溶性高分子、(B)具有烯属不饱和双键的化合物和(C)光聚合引发剂，感光性树脂层压体用于形成导体部的保护膜，感光性树脂层的厚度为20μm以下，且感光性树脂层的固化物满足下述(1)～(3)的条件：(1)交联密度为1,000mol/m3～8,000mol/m3；(2)Tanδ的峰顶值为0.4以上；以及(3)波长532nm下的折射率为1.50～1.60。
Abstract(English):

The present invention provides a photosensitive resin laminate in which (A) an alkali-soluble polymer, (B) a compound having an ethylenically unsaturated double bond, and (C) a photosensitive resin layer including a photopolymerization initiator are laminated on a support film. The photosensitive resin laminate is used in forming the protective film of a conductor part, the thickness of the photosensitive resin is 20 [mu]m or less, and the cured product of the photosensitive resin layer satisfies conditions (1) to (3): (1) the crosslink density is 1,000 mol/m3-8,000 mol/m3; (2) the peak top value of Tan Delta is 0.4 or greater; and (3) the refractive index at a wavelength of 532 nm is 1.50-1.60.
