REACTIVE DILUENT AND CURABLE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a reactive diluent being solid at a room temperature, having excellent curing characteristics and viscosity reducing properties, low skin irritation and excellent adhesion of a composition before curing to a substrate as a polymerizable monomer for curing, a curable resin composition containing the reactive diluent and to provide its use. SOLUTION: This reactive diluent contains an N-vinylacetamide of a polymerizable monomer containing a polar group and having 54-55 deg.C melting point. Consequently the reactive diluent does not impair curing characteristics as a curing resin composition curable by heat, active light rays, etc., and has excellent viscosity reducing properties and low skin irritation. A curable resin composition and its use are provided.
