<P>PROBLEM TO BE SOLVED: To provide a solder resist composition which has high reflection rate and high resolution and prevents the decrease of the reflection rate due to color degradation and to provide a print circuit board obtained by forming a solder resist by using the solder resist composition. <P>SOLUTION: A solder resist composition includes (A) a resin containing carboxyl groups, (B) a photopolymerization initiator based on bisacylphosphine oxide, (C) a photopolymerization initiator based on monoacylphosphine oxide, (D) a melamine or its derivative, (E) a photopolymerizable monomer, (F) a rutile type titanium oxide, (G) an epoxy compound and (H) an organic solvent. <P>COPYRIGHT: (C)2012,JPO&INPIT |
