PROBLEM TO BE SOLVED: To provide a photosensitive solder resist composition having good storage stability and high moisture-heat resistance.SOLUTION: The photosensitive solder resist composition comprises (A) a block isocyanate silane obtained by reacting an isocyanate compound represented by general formula (I) below with a blocking agent, (B) a curable resin, (C) a diluent, (D) a polymerization initiator, and (E) a filler. In the formula, Rrepresents an alkyl group having 1 to 8 carbon atoms; n represents a number of 1 to 10; a represents a number of 1 to 3; and b represents a number of 0 to 2 satisfying a+b=3.SELECTED DRAWING: None |
