PHOTO-SETTING RESIN COMPOSITION

摘要

PURPOSE: To obtain the subject composition useful as a resist ink for printed- wiring boards, etc., providing a resist film having inhibitory effect on change in color of copper and silver and inhibitory effect on migration by blending a specific photo-setting resin with isocyanuric acid and a photopolymerization initiator. CONSTITUTION: This composition comprising (A) a photo-setting resin containing at least one end unsaturated double bond cross-linkable and curable with light energy such as ultraviolet light, (B) isocyanuric acid (e.g. 1-15 pts.wt. based on 100 pts.wt. of the component A) and (C) a photopolymerization initiator (e.g. benzoin). For example, a resin such as an unsaturated polyester resin or a (meth)acrylate-based is preferably used as the component A.
