The present invention provides an acrylic ester compound represented by formula (1), a polymerizable composition containing the acrylic ester compound, and a cured product and an optical component obtained by polymerizing the polymerizable composition:
1
(wherein “a” is an integer of 0 to 4; R
1
is a directly bonded single bond, an alkylene group, an aralkylene group or arylene group which may have a substituent, or a —Y
3
—S—R
4
—S—Y
4
— group (R
4
is an alkylene group, an aralkylene group or an arylene group; and Y
3
and Y
4
are each an alkylene group); R
2
and R
3
are each a hydrogen atom or an alkyl group; X
1
and X
2
are each an oxygen atom or a sulfur atom; and Y
1
and Y
2
are each an alkylene group which may contain an oxygen atom or a sulfur atom).
本发明提供一种由式(1)表示的丙烯酸酯化合物、含有该丙烯酸酯化合物的可聚合组合物以及由聚合可聚合组合物得到的固化产品和光学组件:1(其中“a”为0至4的整数;R1是直接键合的单键、烷基、芳基烷基或芳基基团,该基团可能具有取代基,或者是一个—Y3—S—R4—S—Y4—基团(R4是烷基、芳基烷基或芳基基团;Y3和Y4各自是烷基);R2和R3各自是氢原子或烷基;X1和X2各自是氧原子或硫原子;Y1和Y2各自是可能含有氧原子或硫原子的烷基)。
