PURPOSE: Provided are an adhesive coating of special polymer components, which holds proper adhesion, and loses adhesion when heated to 180-380 deg.C for 60 seconds or more, and thus which is peeled at proper time without remaining residue, and its use. CONSTITUTION: The adhesive coating(10) which is used for adhering a flexible printed circuit board(20) to an insulating board or reinforcing plate(30), is produced by mixing at least any one of hardeners based on imidazole, epoxy, phenol, and alkyl, with a basic mixing ratio of the hardeners to the ink of 6% based on an ink for infrared or heat drying, wherein the amount of added hardeners varies in the range of 2-100% to adjust the adhesion of the coating. The coating is heated at a pressure of 2-60 kgf/cm¬2 and a temperature of 80-200 deg.C for 5 minutes to 1 hour. |
