Abstract
The present invention provides curing combination for stamping, having characters of good stamping and photo-curing, mechanical features and various durability, wherein the photo-curing character, heat resisting property and elastic restitution rate are excellent, condensate using the combination and a method for producing the same, and members for a liquid crystal display device. The curing combination contains optical polymeric monomer, optical polymerization initiator and anti-oxidant, characterized in that a content of the optical polymerism monomer is 80-99% by weight, a content of the anti-oxidant is 0.3-7% by weight, and the anti-oxidant is one of only hindered phenol series anti-oxidant, only semi hindered phenol series anti-oxidant, mixture of hindered phenol series anti-oxidant and semi hindered phenol series anti-oxidant, or only hindered amine series anti-oxidant.
Description
technical field [0001] The present invention relates to a curable composition for imprint, a cured product using the composition, a production method thereof, and a liquid crystal display device member using the cured product. Background technique [0002] As the imprint method, there are proposed two technologies, a thermal imprint method using a thermoplastic resin as a material to be processed (for example, refer to Non-Patent Document 1) and a photoimprint method using a photocurable composition (for example, refer to Non-Patent Document 2). . In the hot imprint method, a mold is pressed against a polymer resin heated to a temperature above the glass transition temperature, and the mold is released after cooling to transfer a fine structure to the resin on the substrate. Since this method can be applied to various resin materials and glass materials, it is expected to be applied to various fields. For example, Patent Documents 1 and 2 below disclose a thermal imprint m...
