PROBLEM TO BE SOLVED: To develop a baking sheet for Al capable of being easily mounted at a flexible aluminum product such as a rolled foil or the like by occasionally imparting information at a job site or the like such as, for example, durable against annealing step condition of 10 and several hours at 530 deg.C. SOLUTION: The baking sheet for the Al comprises a sheet to be baked at the aluminum product (4) to be heat treated, an ink acceptive layer (1) using the inorganic powder and the silicon-containing binder and disposed on a front surface of the sheet for printing, a pressure-sensitive adhesive layer (2) on the rear surface of the sheet for printing. In this baking sheet, the silicon-containing binder is made of a polymer of a trimethylsiloxysilicic acid or an M unit represented by R3 SiO- and a Q unit represented by Si(O-)4 , and ink information can be imparted to the ink acceptive layer by a thermal transfer method. The baking sheet is obtained by temporarily bonding a printing sheet obtained by imparting thermal transfer ink information (3) to the ink acceptive layer of the baking sheet for the Al to the aluminum product via the pressure-sensitive adhesive layer, and baking the printing sheet at 200 deg.C or higher. |
