Title:
ポリチオール化合物を含有する光学材料組成物
Document Type and Number:
Japanese Patent JP7368575
Kind Code:
B2
Abstract:
The invention belongs to the field of high polymer materials, and relates to an optical material composition containing a polythiol composition, the composition contains a first polythiol compound and a second polythiol compound, and also contains an episulfide compound and a polyisocyanate compound, wherein the adding amount of the first polythiol compound is 0.01%-5% of the weight of the whole optical material composition, the toughness of the optical material prepared from the composition is enhanced, meanwhile, the problems of material lines, white turbidity and the like caused by reaction heat release or too fast curing are avoided, and meanwhile, the refractive index and the Abbe number of the optical material are balanced.
