Title:
複合回折光学素子用の高屈折率低分散樹脂用組成物、及び、それを用いた複合回折光学素子
Document Type and Number:
Japanese Patent JP6943238
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing: a composition for high refractive index low dispersion resins for close-contact double layer type composite diffraction optical elements, which has good photocurability and high productivity; and a close-contact double layer type composite diffraction optical element which uses this composition for high refractive index low dispersion resins for close-contact double layer type composite diffraction optical elements. The above-described problem is solved by a composition for high refractive index low dispersion resins for close-contact double layer type composite diffraction optical elements, which contains a thiol compound represented by general formula (1) or an oligomer that is synthesized using a thiol compound represented by general formula (1) (component A) and an ene compound having two or more polymerizable unsaturated bonds (component B). (In the formula, p represents an integer of 2-5; each of X p and Z p independently represents a hydrogen atom or a mercaptomethyl group; the ratio of sulfur atoms in each molecule is 40-80% by mass; and the number of thiol groups is 3 or more.)
