Abstract:
To provide a transparent laminate having a pair of transparent substrates integrated via an adhesive layer, in which the adhesive layer has good tear resistance and good adhesion to the transparent substrates and has excellent transparency.In a first atmosphere, a sealed space having a curable resin composition 14 accommodated between a pair of transparent substrates 10a and 10b, is formed, and then the curable resin composition 14 is cured in a state where the outside of the sealed space is made to be a second atmosphere having a pressure higher than the first atmosphere. As the above curable resin composition, a curable resin composition comprising a urethane oligomer (a) having from 1.8 to 4 curable functional groups on average which are either or both of an acryloyloxy group and a methacryloyloxy group, per molecule, and a hydroxyalkyl methacrylate (b) having a C3-8 hydroxyalkyl group having 1 or 2 hydroxy groups, is used.
