Title:
HARDENING ACCELERATOR FOR CATIONIC POLYMERIZATION TYPE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2004/029126
Kind Code:
A1
Abstract:
A hardening accelerator for cationic polymerization type composition, and a composition containing the same. In particular, a hardening accelerator for use in cationic polymerization type composition, the cationic polymerization type composition excelling in surface hardening characteristics and hardening rate in air and capable of providing a hardened film of excellent adherence and surface hardness; and a composition containing the hardening accelerator. Compound (A) having in its molecule one or more substituents of the following general formula (1) alone realizes rapid initiation of cationic polymerization and induces rapid growing reaction. Further, the compound (A) can be used as a hardening accelerator for compounds having one or more ring-opening type cyclic ether groups in each molecule. (1) wherein R1 represents a C1-C6 branched or unbranched alkyl, and Z represents an oxygen atom.
