PURPOSE:To provide a photosensitive resin compsn. contg. easily available and easily introduced photosensitive groups, having satisfactory shelf stability, heat stability, practical physical properties and sensitivity and not causing cracking at the time of development. CONSTITUTION:This photosensitive resin compsn. consists of 100 pts.wt. polyimide, 10-100 pts.wt. isocyanurate contg. a (meth)acrylic group, 10-100 pts.wt. polyalkylene glycol di(meth)acrylate and 0.5-20 pts.wt. photopolymn. initiator. This compsn. is easily produced, maintains satisfactory practical sensitivity even to a thick film and hardly undergoes a change in the film thickness with the lapse of time or a change in the sensitivity.
