    • The invention relates to a process for preparing a dry film resist by forming a photocurable resin composition onto a support film with a thickness of 1 to 50 mum and optionally laminate a protective film onto the photocurable composition layer to obtain a dry film resist; whereby the photocurable resin is formed from a homogeneous mixture comprising (a) from 20-90wt% of an alkaline soluble binder oligomer or polymer; (b) from 5 to 60wt% of one or more photopolymerizable monomers which are compatible with the oligomers and polymers of component (a); (c) from 0.01 to 20% by weight of one or more photoinitiators; (d) from 0 to 20% by weight of additives and/or assistants; and (e) from 0.1 to 10 % by weight of a leuco triphenylmethane dye of the formula (I), wherein R1 is a residue selected from (II), R2 is C1-C12 alkyl or phenyl which may be mono-, di- or tri-substituted by C1-C 6 alkyl, trifluoromethyl, C1-6 alkoxy, C1- 6 alkylthio, halogen and nitro; R3 is hydrogen or C 1-C12 alkyl; R4 to R9 independently of one another are hydrogen or C1-C12 alkyl; X is O, S, NH or N-C1-C12-alkyl; (a) to (e) being 100% by weight. The above composition is useful to avoid unfavourable colour generation during the heat lamination.
    • 本发明涉及一种制备干膜抗蚀剂的方法,该方法是将光固化性树脂组合物形成在厚度为1〜50μm的载体膜上,任选地将保护膜层叠在光固化性组合物层上,得到干膜抗蚀剂; 由此可光固化树脂由包含(a)20-90重量%的碱溶性粘合剂低聚物或聚合物的均匀混合物形成; (b)5至60重量%的一种或多种与组分(a)的低聚物和聚合物相容的可光聚合单体; (c)0.01至20重量%的一种或多种光引发剂; (d)0至20重量%的添加剂和/或助剂; 和(e)0.1至10重量%的式(I)的无色三苯甲烷染料,其中R 1是选自(II)的残基,R 2是C 1 -C 12烷基或苯基,其可以是单 - ,二 - 或被C 1 -C 6烷基,三氟甲基,C 1-6烷氧基,C 1-6烷硫基,卤素和硝基三取代。 R3是氢或C 1 -C 12烷基; R 4至R 9彼此独立地为氢或C 1 -C 12烷基; X是O,S,NH或N-C 1 -C 12 - 烷基; (a)至(e)为100重量%。 上述组合物可用于在热层压期间避免不利的颜色产生。
