    • PROBLEM TO BE SOLVED: To provide a photocurable composition that is rapidly curable by an active energy ray such as ultraviolet, and is excellent in low viscosity and high elongation property, an adhesive and particularly an adhesive for filling the space of an image display device, which can be obtained using the composition, and an image display device produced using the adhesive.SOLUTION: The photocurable composition that is used for an adhesive comprises as essential components, a vinyl polymer having a group represented by (a) general formula (1): -OC(O)C(R)=CH(wherein Rdenotes a hydrogen atom or a 1-20C organic group), a compound other than component (a) having one or more groups represented by (b) general formula (2): -OC(O)C(R)=CHat the molecular end (wherein Rdenotes a hydrogen atom or 1-20C organic group), and a compound having one or more mercapto groups within molecule (c).
    • 要解决的问题:为了提供可通过诸如紫外线的活性能量射线快速固化的光固化性组合物,并且具有优异的低粘度和高延伸性能,粘合剂,特别是用于填充图像空间的粘合剂 显示装置,以及使用该粘合剂制造的图像显示装置。 用于粘合剂的光固化性组合物包含作为必要成分的具有(a)通式(1)表示的基团的乙烯基聚合物:-OC(O)C(R a )= CH 2 (其中R a 表示氢原子或1-20C有机基团 ),具有一个或多个由(b)通式(2)表示的基团的组分(a)以外的化合物:-OC(O)C(R b )= CH 在分子末端(其中R b 表示氢原子或1-20C有机基团)和具有一个 或更多的巯基分子(c)。 版权所有(C)2012,JPO&INPIT
