Problems solved by technology

When the inventors of the present invention produced these resin compositions, they found that in the latter resin composition, the miscibility (compatibility) of the resin and BCF was low, and although it seemed to have transparency, when it was subjected to heat pressing, molding, etc., Sometimes the resin composition becomes cloudy, and the Abbe number cannot be measured in some cases
In addition, it was found that the heat resistance (glass transition temperature) of these resin compositions was insufficient
Therefore, it was found that it cannot be utilized in applications such as optical lenses

Embodiment 1

[0143] 85 parts by weight of pellets of "ARTON" (manufactured by JSR Co., Ltd., F4520, Tg=164°C, Mw=60000) as a cyclic olefin resin, and 9,9-bis(4-(2 -Hydroxyethoxy) phenyl) fluorene (manufactured by Osaka Gas Chemical Co., Ltd., hereinafter referred to as BPEF) 15 parts by weight is kneaded using a twin-screw extruder (manufactured by Technobell, model KZW15 / 45), extruded The strand material was discharged and cut with a cutter to obtain pellets. The appearance of the resin composition was a colorless and transparent pellet.

Embodiment 2

[0145] Except having used 90 weight part of cyclic olefin resins and 10 weight part of BPEF, it carried out similarly to Example 1, and obtained the resin composition.

Embodiment 3

[0147] Except having used 95 weight part of cyclic olefin resins and 5 weight part of BPEF, it carried out similarly to Example 1, and obtained the resin composition.

Abstract

The present invention relates to a resin composition obtained by adding a compound which has polar substituents, is represented by the following formula (2), and includes a 9,9-bisarylfluorene skeleton, to a cycloolefin-based resin having a functional group, the resin composition having a moderate Abbe number. [In the formula, ring Z represents an arene ring; R3 and R4 each represent a substituent; group X represents -[(OR5)n1-Y1] (wherein substituent Y1 represents a hydroxyl, mercapto, glycidyloxy, or (meth)acryloyloxy group, R5 represents an alkylene group, and n1 is 0 or an integer of 1 or larger) or -[(CH2)n2-Y2] (wherein substituent Y2 represents a carboxyl, alkoxycarbonyl, amino, or substituted amino group and n2 is 0 or an integer of 1 or larger); k is an integer of 0-4; m is 0 or an integer of 1 or larger; and p is an integer of 1 or larger.] This resin composition has an Abbe number in an intermediate range (Abbe number of about 28-55) and is useful as an optical lens, etc.

Description

technical field [0001] The present invention relates to a resin composition useful as an optical lens including a compound having a cyclic olefin resin and a 9,9-bisarylfluorene skeleton (hereinafter also referred to as a fluorene compound in some cases). Background technique [0002] Cyclic olefin-based resins have excellent characteristics such as high transparency, high heat resistance, and low birefringence, so they are used in optical materials, such as photographic lenses (or optical lenses) included in portable communication devices such as mobile phones and smartphones. ) and so on. [0003] In recent years, as such mobile phones and smartphone terminals have become thinner and more multifunctional, there has been a demand for miniaturization of imaging lenses mounted in imaging devices in order to ensure space for mounting components and elements. In addition, along with miniaturization, higher pixel resolution of imaging elements such as sensors using charge-coupl...
