Title:
POLYMERIZABLE COMPOSITION FOR OPTICAL MATERIAL, METHOD FOR PRODUCING SAME, AND OPTICAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2024/071346
Kind Code:
A1
Abstract:
This polymerizable composition for an optical material contains: a polyisocyanate (a) that contains an aliphatic polyisocyanate (a1) and a modified aliphatic polyisocyanate (a2); a polythiol composition (b) that contains a polythiol compound; and a compound (c) that is represented by formula (1). R1 through R8 each independently represent a group represented by formula (2), a C1 to C20 alkyl group, a C1 to C20 alkoxy group, a hydroxy group, or a polysiloxy group. However, at least one of R1 through R8 is a group represented by formula (2). m and n each independently represent an integer of zero or higher. R25 represents a C1 to C20 alkylene group or the like, k represents an integer of one or higher, and * represents a binding position.
