摘要:
A photosensitive resin composition which gives a dry film having a sand blast proof property and a development property in a well-balanced manner. A photosensitive resin composition containing a carboxy group-containing urethane (meth)acrylate compound having two or more of (meth)acryloyl groups per molecule whose acid value of less than 10 mg KOH/g, an alkali soluble polymer compound, a photopolymerization initiator and a photopolymerizable compound (D) including in the structure thereof a structural unit represented by the formula (I) gives such a well-balanced properties.
