３秒のタイムラグが必要となる。Upon curing, an electron beam of 1 to 5 Mrad is irradiated. At this time, it is necessary to ensure that the electron beam curable resin has penetrated and reached the interface of the layer of the heat-sensitive adhesive on the back surface before being irradiated with the electron beam. For example,
When the paper is titanium paper of 50 g / m 2 and the viscosity of the electron beam curable resin is 30 to 150 cps, it is 2 to from the application of the electron beam curable resin to the curing by the electron beam irradiation.
A time lag of 3 seconds is required.
