PROBLEM TO BE SOLVED: To provide a coating resin composition that achieves shortened process time, enhanced processing yield and increased positioning accuracy.SOLUTION: A guide sheet 1 is produced by coating a photosensitive resin composition 20 onto an aluminum foil sheet 10 and bonding the coating resin 20 onto the aluminum foil sheet 10 by photo-curing. The resin composition 20 includes a first polymer produced by reacting 1,2,4,5-pyromellitic acid anhydride and a polyether amine and a second polymer produced by reacting a polyether amine and chloroethylene in which the second polymer is a photosensitive polymer. When the novel resin composition is coated onto a guide sheet 1 for boring and the guide sheet 1 for boring is applied to a boring process, the effect of enhancing stability, accuracy and precision of boring is achieved without causing cracking of the coating resin 20 by high temperature due to friction under high rotational speed of boring.SELECTED DRAWING: Figure 1 |
