Phosphorus-containing (meth)acryloyl compound, phosphorus-containing vinyl benzyl compound, production methods therefor, and flame-retardant resin composition and laminated board for electronic circuit board containing same

Abstract

Provided is a phosphorus-containing compound that is useful as a reactive phosphorous-based flame retardant and yields a cured product having excellent heat resistance and dielectric properties, a curable resin composition containing the phosphorus-containing compound, and a cured product thereof. Phosphorus-containing (meth)acryloyl compound or phosphorus-containing vinylbenzyl ether compound represented by general formula (1). In the general formula (1), Ar is an aromatic cyclic group having 6 to 30 carbon atoms optionally having a substituent, R1 is each independently a substituent represented by the following general formula (2) or (3), provided that the compound contains at least one substituent represented by the general formula (2) and at least one substituent represented by the general formula (3), and m is an integer of 3 to 6.
