Patent ID: 8044235

Claim:
A process for producing an aromatic isocyanate compound containing a (meth)acryloyl group, the compound being represented by Formula (I): wherein R 1 is a single bond or a linear or branched alkylene group of 1 to 5 carbon atoms, R 2 is a hydrogen atom or a methyl group, R 3 is a single bond, X is independently a halogen atom or an electron-withdrawing group, m is an integer ranging from 0 to 4, n is an integer ranging from 1 to 3, and 1≦m+n≦5, the process comprising the following steps (1′) to (3′): (1′) a step of reacting a hydroxyphenylamine compound and a mineral acid to obtain a hydroxyphenylamino mineral acid salt compound, the hydroxyphenylamine compound being represented by Formula (V): wherein R 1 , R 3 , X, m and n are as defined in Formula (I), the hydroxyphenylamino mineral acid salt compound being represented by Formula (VI): wherein R 1 , R 3 , X, m and n are as defined in Formula (I), and W 1 is the mineral acid; (2′) a step of reacting the hydroxyphenylamino mineral acid salt compound obtained in the step (1′) and a compound represented by Formula (VII) to obtain a hydroxyphenyl isocyanate compound: wherein Z 1 and Z 2 are each a fluorine atom, a chlorine atom, a bromine atom, an imidazole, a pyrazole or R′O— wherein R′ is an alkyl or alkenyl group of 1 to 6 carbon atoms that is a straight chain or has a branch, or an aryl group that is unsubstituted or is substituted with a substituent group, the hydroxyphenyl isocyanate compound being represented by Formula (VIII): wherein R 1 , R 3 , X, m and n are as defined in Formula (I); and (3′) a step of reacting the hydroxyphenyl isocyanate compound obtained in the step (2′) with a compound represented by Formula (XI): wherein R 2 is as defined in Formula (I).
