  • Patent number: 8734955
    Abstract: A transparent laminate is produced by preparing a pair of transparent substrates, forming a sealing portion along the periphery on one of the transparent substrates for sealing a curable resin composition, supplying the curable resin composition in a region on the transparent substrate surrounded by the sealing portion, overlaying the other transparent substrate on the supplied curable resin composition in a reduced pressure atmosphere so that the curable resin composition is sealed as it is sandwiched between the pair of transparent substrates, and subsequently curing the curable resin composition in an atmosphere having a higher pressure than the pressure of the atmosphere in which the composition is sandwiched, to produce the transparent laminate.

  • Patent number: 8592039
    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.
