Claim Text:
1. A method of manufacturing a translucent rigid substrate laminate, comprising: 1) a process of preparing a first translucent rigid substrate; 2) a process of preparing a second translucent rigid substrate; 3) a process of applying a photo-curable fixing agent including (A) polyfunctional (meth)acrylate, (B) monofunctional (meth)acrylate and (C) a photopolymerization initiator to a first surface of the first translucent rigid substrate and/or a first surface of the second translucent rigid substrate; 4) a process of allowing the first surface of the first translucent rigid substrate and the first surface of the second translucent rigid substrate to face each other so that the both surfaces are parallel to each other in a predetermined positional relationship in a surface direction; 5) a process of applying a pressure of 5 to 50 g/cm 6) a process of irradiating light each time to the surface of the second translucent rigid substrate for curing the entire fixing agent interposed and spreading between both translucent rigid substrates while applying the pressure of 5 to 50 g/cm wherein a relationship between an intensity of light to be irradiated in the process 6) and a thickness of the fixing agent is set so that light does not substantially pass through a new bonding surface on which the fixing agent that is uncured exists, 7) a process of repeating the processes 1) to 6) at least once by regarding the translucent rigid substrate laminate as the first translucent rigid substrate to form a translucent rigid substrate laminate in which at least three translucent rigid substrates are bonded.
