Problems solved by technology

However, the use of the above-mentioned antioxidants is not sufficient for the oxidation resistance under high temperature conditions (for example, about 260° C.) such as soldering using a reflow method. Especially when used as a material for optical members such as lenses, it inhibits yellowing completely inadequate
Therefore, for example, a mobile phone with a camera is often manufactured through a process of connecting a separately produced camera module with a connector after a soldering process (mounting process) using a reflow method, and the manufacturing process becomes complicated.

Embodiment 1

[0163] According to the epoxy compound [2,2-bis(hydroxymethyl)-1-butanol of 1,2-epoxy-4-(2-epoxyethyl)cyclohexane adduct, contained in the above formula ( Among the compounds shown in A2-2), Daicel Chemical Industry Co., Ltd. manufactures, trade name "EHPE 3150"] 30 parts by weight, (meth)acrylate [tricyclo[5.2.1.0 2，6 ] decane dimethanol diacrylate, contained in the compound represented by the above formula (B2-1), manufactured by Daicel-Cytec Company, trade name "IRR 214K"] 50 parts by weight, (methyl) with epoxy group Acrylates [epoxidized dicyclopentenyl acrylate (=3,4-epoxytricyclo[5.2.1.0 2，6 ]decane-8-yl acrylate and 3,4-epoxytricyclo[5.2.1.0 2,6 ] Decane-9-yl acrylate, contained in the compound shown in the above formula (C1-1), manufactured by Daicel Chemical Industry Co., Ltd., trade name "E-DCPA"] 20 parts by weight, acid generator (arylsulfonium Salt acid generator San-Apro, trade name "CPI-100P") 1 part by weight, free radical initiator (acetophenone radical ini...

Embodiment 2

[0166] 1,10-Decanedithiol (HS-C 10 h 21 -SH) instead of decylthiol, it carried out similarly to Example 1, and obtained the cured resin.

Embodiment 3

[0168] Using didecyl sulfide (n-decyl sulfide; C 10 h 21 -S-C 10 h 21 ) instead of decylmercaptan, except that, it was the same as in Example 1 to obtain a cured resin.

Abstract

Disclosed is a curable composition which produces a cured resin resistant to yellowing even under high temperature conditions such as reflow method soldering. The curable composition comprises a cationic polymer compound and at least one organic sulphur compound selected from the group of thiol compounds, dithiol compounds, sulphide compounds and disulphide compounds. It is preferable that the organic sulphur compound has a boiling point of 100 DEG C or above. Additionally, it is preferable that the cationic polymer compound is composed of at least one of the group of epoxy compounds, oxetane compounds and vinyl ether compounds.

Description

technical field [0001] The present invention relates to a curable composition, its cured product, and an optical member. More specifically, it relates to a curable composition capable of forming a cured product that is not easily yellowed even at high temperatures, a cured resin that is obtained by curing the curable composition, and a lens formed of the cured resin. and other optical components. Background technique [0002] Deterioration and yellowing of resin materials, especially deterioration and yellowing due to oxidation are extremely serious problems. Resin materials are basically oxidatively degraded in the presence of oxygen, but this oxidative degradation is often caused by energy such as ultraviolet rays or heat. For thermoplastic resins such as polyolefins and engineering plastics, various stabilizers are added to prevent deterioration during heating during molding or long-term use of molded products. method, the method of using antioxidants is widely used. ...
