WHITE ALKALI-DEVELOPABLE PHOTOCURABLE AND THERMOSETTING SOLDER RESIST COMPOSITION, AND METAL-BASE CIRCUIT SUBSTRATE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a high-reflectance alkali-developable photocurable and thermosetting solder resist composition, and a metal-base circuit substrate using the same having a high reflection function.;SOLUTION: The white alkali-developable photocurable and thermosetting solder resist composition comprises (A) a carboxyl-containing (meth)acrylate having no aromatic ring, (B) a (meth)acryl compound, (C) a photopolymerization initiator, (D) an epoxy compound, (E) a curing agent for thermosetting, (F) a curing catalyst for thermosetting, (G) inorganic powder, and (H) an organic solvent. The metal-base circuit substrate comprises an insulating layer formed on metal foil, and a circuit formed on the insulating layer wherein a white film is formed on the insulating layer and the circuit using the solder resist composition.;COPYRIGHT: (C)2009,JPO&INPIT
