    • A functional laminated spectacle lens is provided which includes, as constituent layers, an outer lens (1), a polarizing film (2), and an inner lens (3) which are layer parts, and which is obtained by: forming a functional layer(s) (D 1 , D 2 , D 3 and/or D 4 ,) on at least one of the constituent layers; forming adhesive layers (4 and 5) on the functional layer(s); and laminating and integrating other constituent layers, with the adhesive layers (4 and 5) being interposed therebetween. In the functional laminated spectacle lens, each of the functional layers (D 1 , D 2 , D 3 and D 4 ,) is formed using a spin coating material, which is characterized by being obtained by incorporating a functional pigment into an acrylic urethane resin which comprises, as a main component, an acrylic polyol containing 4-hydroxybutyl acrylate, and, as a curable component, a polyisocyanate. In the functional layer obtained by curing the spin coating material, the required functional pigment is reliably maintained in the functional layer by a three-dimensional network structure, the migration of the functional pigment into an adjacent resin monomer-containing layer is prevented, and the functional pigment is made less susceptible to the effect of an organic peroxide contained in the resin.
    • 提供了一种功能性层压眼镜镜片,其包括作为构成层的作为层状部件的外透镜(1),偏振膜(2)和内透镜(3),并且其通过以下方式获得:形成功能层 (D 1,D 2,D 3和/或D 4)在至少一个构成层上; 在功能层上形成粘合剂层(4和5); 并将其他的构成层层叠并一体化,在其间夹着粘接层(4和5)。 在功能性层压眼镜镜片中,功能层(D 1,D 2,D 3和D 4)中的每一个都使用旋涂材料形成,其特征在于通过将功能性颜料结合到丙烯酸聚氨酯树脂 其包含作为主要组分的含有丙烯酸4-羟丁酯的丙烯酸多元醇和作为可固化组分的多异氰酸酯。 在通过固化旋涂材料获得的功能层中,所需功能颜料通过三维网状结构可靠地保持在功能层中,防止了功能颜料向相邻含树脂单体层的迁移,并且 功能性颜料不易受到树脂中所含的有机过氧化物的影响。
