Document Type and Number:
Japanese Patent JP6610981
Kind Code:
B2
Abstract:
Provided is a prepreg resin composition, containing: a urethane (meth)acrylate (A) that is a reaction product of polyisocyanate (a1), polyol (a2), and hydroxy alkyl (meth)acrylate (a3); and a polymerization initiator (B), as an essential component, in which the polyisocyanate (a1) is at least one polyisocyanate selected from 2,4'-diphenyl methane diisocyanate, 4,4'-diphenyl methane diisocyanate, a carbodiimide modified product of 4,4'-diphenyl methane diisocyanate, and polymethylene polyphenyl polyisocyanate, and the polyol (a2) has an aromatic-ring and an oxyalkylene structure. The prepreg resin composition of the invention is excellent in workability and molding properties, and is capable of forming a molded article excellent in various physical properties such as external appearance and heat resistance, and thus, can be preferably used in a prepreg and a molded article thereof.
