METHOD OF MANUFACTURING TRANSLUCENT RIGID SUBSTRATE LAMINATE AND TRANSLUCENT RIGID SUBSTRATE BONDING APPARATUS

摘要

Provided is a method of manufacturing a translucent rigid substrate laminate, which method can improve position precision while increasing production efficiency. Further provided is a translucent rigid substrate bonding apparatus that contributes to improvement of the position precision while increasing production efficiency of a plate-shaped product. In the method of manufacturing a translucent rigid substrate laminate and the translucent rigid substrate bonding apparatus according to the present invention, when translucent rigid substrates are bonded in a predetermined positional relationship by interposing a photo-curable fixing agent including (A) polyfunctional (meth)acrylate, (B) monofunctional (meth)acrylate and (C) a photopolymerization initiator therebetween, only the fixing agent present in outer peripheral portions of both translucent rigid substrates is cured for provisional fastening.

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 given pressure to the first surface of the first translucent rigid substrate and the first surface of the second translucent rigid substrate while maintaining the positional relationship to bond the both translucent rigid substrates; 6) a process of irradiating light for curing only an outer peripheral portion of the fixing agent spreading between the both translucent rigid substrates to form a provisionally fastened translucent rigid substrate laminate; 7) a full fastening process of curing the uncured fixing agent present in the provisionally fastened translucent rigid substrate laminate to form a fully fastened translucent rigid substrate laminate; and 8) a process of repeating the processes 1) to 7) at least once by regarding the fully fastened translucent rigid substrate laminate as the first translucent rigid substrate to form a fully fastened translucent rigid substrate laminate in which at least three translucent rigid substrates are bonded.
