Examples of resins used in the resin film-forming composition include the resins described above. (Meth)acrylic resins, polyester fibers, cyclic olefin resins, and cellulose acylate resins are preferred, with cellulose acylate resins being more preferred. The resin film-forming composition can contain additives described in paragraphs 0022 to 0067 of JP 2012-215689 A. Examples of such additives include sugar esters. Adding a sugar ester compound to a resin film-forming composition containing a cellulose acylate resin can reduce total haze and internal haze without impairing the expression of optical properties and even without heat treatment before the stretching process. Furthermore, a resin film (cellulose acylate film) using a composition containing a cellulose acylate resin can be produced by the method described in paragraphs 0068 to 0096 of JP 2012-215689 A. Furthermore, the resin film may further be laminated with a hard coat layer described in paragraphs 0097 to 0113 of JP-A No. 2012-215689.

[0214] Another example of an optical member is an optical member having a laminate of a support and a resin layer, in which at least one of the support and the resin layer contains the cured product of the present invention.

[0215] The thickness of the resin layer in the laminate is preferably 1 μm to 2500 μm, and more preferably 10 μm to 500 μm.

[0216] The support in the laminate is preferably a material that has transparency to the extent that the optical performance is not impaired. The support being transparent means that the support is optically transparent, specifically, that the support has a total light transmittance of 85% or more. The total light transmittance of the support is preferably 90% or more, and more preferably 95% or more.

[0217] A suitable example of the support is a resin film. Examples of resins constituting the resin film include ester resins (e.g., polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycyclohexane dimethylene terephthalate (PCT), etc.), olefin resins (e.g., polypropylene (PP), polyethylene (PE), etc.), polyvinyl chloride (PVA), tricellulose acetate (TAC), etc. Among these, PET is preferred in terms of versatility.

[0218] The thickness of the support can be appropriately selected depending on the use or purpose, etc. In general, the thickness is preferably from 5 μm to 2500 μm, and more preferably from 20 μm to 500 μm.

[0219] The support may also be a releasable support. Such a laminate is preferably used for a polarizing plate or the like. Here, the releasable support refers to a support that can be peeled from the resin film. The stress when peeling the support from the resin film is preferably 0.05 N / 25 mm or more and 2.00 N / 25 mm or less, more preferably 0.08 N / 25 mm or more and 0.50 N / 25 mm or less, and even more preferably 0.11 N / 25 mm or more and 0.20 N / 25 mm or less. The stress when peeling the support from the resin film was evaluated by first cutting a piece of the laminate to a width of 25 mm and a length of 80 mm, and then bonding and fixing the surface of the piece to a glass substrate via an acrylic adhesive sheet. Then, using a tensile tester (RTF-1210 manufactured by A&D Co., Ltd.), one longitudinal end of the test piece (one side of the 25 mm width) was gripped and a 90° peel test (based on Japanese Industrial Standards (JIS) K 6854-1:1999 "Adhesives - Test method for peel adhesion strength - Part 1: 90° peel") was performed in an atmosphere of 23°C and 60% relative humidity at a crosshead speed (grip movement speed) of 200 mm / min.

[0220] The peelable support preferably contains polyethylene terephthalate (PET) as the main component (the component with the highest mass content among the components constituting the support). From the viewpoint of mechanical strength, the weight-average molecular weight of PET is preferably 20,000 or more, more preferably 30,000 or more, and even more preferably 40,000 or more. The weight-average molecular weight of PET can be determined by dissolving the support in hexafluoroisopropanol (HFIP) and using the GPC method described above. The thickness of the support is not particularly limited, but is preferably 0.1 to 100 μm, more preferably 0.1 to 75 μm, even more preferably 0.1 to 55 μm, and particularly preferably 0.1 to 10 μm.

Such a laminate is preferably used as an ultraviolet cut filter or a protective material (protective film, protective sheet). In this type of optical component, any of the support, the hard coat layer, and the pressure-sensitive adhesive layer or adhesive layer may contain the cured product of the present invention.

[0222] Examples of hard coat layers include those described in JP 2013-045045 A, JP 2013-043352 A, JP 2012-232459 A, JP 2012-128157 A, JP 2011-131409 A, JP 2011-131404 A, JP 2011-126162 A, JP 2011-075705 A, JP 2009-286981 A, JP 2009-263567 A, JP 2009 The hard coat layer described in JP-A-2007-075248, JP-A-2007-164206, JP-A-2006-096811, JP-A-2004-075970, JP-A-2002-156505, JP-A-2001-272503, WO 2012 / 018087, WO 2012 / 098967, WO 2012 / 086659, and WO 2011 / 105594 can be applied. The thickness of the hard coat layer is preferably 5 to 100 μm in order to further improve scratch resistance.

[0223] This optical component has a pressure-sensitive adhesive layer or bonding layer on the side of the supporting substrate opposite the side having the hard coat layer. The type of pressure-sensitive adhesive or bonding agent used in the pressure-sensitive adhesive or bonding layer is not particularly limited, and known pressure-sensitive adhesives or bonding agents can be used.
