    • Provided is an optical element material characterized in being obtained by curing a resin composition for photoimprinting, wherein the content weight ratio of a photocurable monomer (A) represented by formula (1) and a photocurable monomer (B) represented by formula (2) is 30/70 to 87/13, and the content of a photopolymerization initiator (C) is 0.01 to 30 parts by weight per the total of 100 parts by weight of the photocurable monomer (A) and the photocurable monomer (B). Also provided is a method for producing the same.

      In formula (1), R 1 is a -CH=CH 2 , -CH 2 CH 2 -O-CH=CH 2 , -CH 2 CH 2 -O-CO-CH=CH 2 , -CH 2 CH 2 -O-CO-C(CH 3 )=CH 2 , -CH 2 -C(CH 3 ) =CH 2 or a glycidyl group; R 2 and R 3 are the same or different and are hydrogen or a C 1-4 alkyl group. In formula (2), R 4 and R 5 are the same or different and -O-CH=CH 2 , O-CH 2 CH 2 -O-CH=CH 2 , -O-CO-CH=CH 2 , O-CO-C(CH 3 ) =CH 2 , -O-CH 2 CH 2 -O-CO-CH=CH 2 , -O-CH 2 CH 2 -O-CO-C(CH 3 ) =CH 2 or glycidyl ether groups. R 6 and R 7 are the same or different and are hydrogen or C 1-4 alkyl groups.
    • 提供一种光学元件材料,其特征在于通过固化光密封用树脂组合物获得,其中由式(1)表示的光固化性单体(A)和由式(2)表示的光固化性单体(B)的含量重量比为 30/70〜87/13,光聚合引发剂(C)的含量相对于100重量份的光固化性单体(A)和光固化性单体(B)的总计为0.01〜30重量份。 还提供了其制造方法。 式(1)中,R 1为-CH = CH 2,-CH 2 CH 2 -O-CH = CH 2,-CH 2 CH 2 -O-CO-CH = CH 2,-CH 2 CH 2 - O-CO-C(CH 3)= CH 2,-CH 2 -C(CH 3)= CH 2或缩水甘油基; R 2和R 3相同或不同,为氢或C 1-4烷基。 在式(2)中,R 4和R 5相同或不同,-O-CH = CH 2,O-CH 2 CH 2 -O-CH = CH 2,-O-CO-CH = CH 2,O -CO-C(CH 3)= CH 2,-O-CH 2 CH 2 -O-CO-CH = CH 2,-O-CH 2 CH 2 -O-CO-C(CH 3)= CH 2或 缩水甘油醚基团。 R 6和R 7相同或不同,为氢或C 1-4烷基。
