PURPOSE:To exfoliate a substance to be printed from a reinforcing material without leaving an adhesive on the substance to be printed, by making an exfoliation strength between the material and an adhesive layer larger than one between the adhesive layer and the substance to be printed, when the substance to be printed is laminated on the reinforcing material through the intermediary of a hot melt type adhesive. CONSTITUTION:As for a first layer A of a laminate for offset printing, textile, knit or a film is used as a material for a substance to be printed. As adhesive of a second layer B is of a hot melt type and polyolefin, polyamide or polyurethane is used therefor. A third layer C is made up of a reinforcing material and paper, synthetic paper or the film is used therefor. While an exfoliation strength between the first and second layers is made to be 10 to 700g/inch, the strength between the second and third layers is made still larger, and the flexural stiffness of an entire laminate is made to be 0.40g.cm<2>/cm or above. |
