Abstract

A reaction accelerator is provided which is used in a reaction of a compound including an isocyanate group that is not directly bonded to an aromatic ring in a molecule with a compound including an active hydrogen-containing group and is formed of a compound including a halogenated carbamoyl group. A production method is provided which includes reacting a compound including an isocyanate group that is not directly bonded to an aromatic ring in a molecule with a compound including an active hydrogen-containing group to produce a urethane compound, a thiourethane compound, an amide compound or a urea compound, in which the reaction is performed in the presence of the reaction accelerator.

First claim

1 . A reaction accelerator, wherein
the reaction accelerator is used in a reaction of a compound comprising an isocyanate group in a molecule, in which the isocyanate group is not directly bonded to an aromatic ring, with a compound including an active hydrogen-containing group, and the reaction accelerator is a compound including a halogenated carbamoyl group.

2 . The reaction accelerator according to claim 1 , wherein the reaction is a reaction that generates a urethane compound, a thiourethane compound, an amide compound or a urea compound.

3 . The reaction accelerator according to claim 1 , wherein the compound comprising an isocyanate group that is not directly bonded to an aromatic ring in a molecule is at least one selected from a group consisting of hexamethylene diisocyanate, trimethyl hexamethylene diisocyanate, lysine diisocyanate, norbornane diisocyanate, trans-cyclohexane-1,4-diisocyanate, isophorone diisocyanate, bis(isocyanate methyl)cyclohexane, dicyclohexylmethane diisocyanate, dimer acid diisocyanate, m-xylene diisocyanate, m-tetramethylxylene diisocyanate, other diisocyanate compounds represented by the general formula OCN—R—NCO (R represents a divalent aliphatic residue having 1 to 20 carbon atoms), methacroyl isocyanate, 3-isopropenyl-α,α-dimethylbenzyl isocyanate, 3-isocyanatepropyl trimethoxysilane, methacryloyloxyethyl isocyanate, acryloyloxyethyl isocyanate, 1,1-(bisacryloyloxymethyl)ethyl isocyanate, methacryloyloxyethoxyethyl isocyanate, acryloyloxyethoxyethyl isocyanate, and other monoisocyanate compounds represented by the general formula R″—NCO (R″ represents a monovalent aliphatic residue having 1 to 20 carbon atoms).

4 . The reaction accelerator according to claim 1 , wherein the active hydrogen-containing group is a hydroxyl group, a mercapto group, a carbonyl group, or an amino group.

5 . The reaction accelerator according to claim 1 , further comprising a (meth)acryloyl group.

6 . The reaction accelerator according to claim 1 , wherein the accelerator is a compound represented by the following general formula (I-1) or (I-2)

wherein, in the formulae, R 1 and R 2 each independently represent a hydrogen atom or a methyl group, R 3 represents an alkylene group which may include a substituent and has 1 to 10 carbon atoms or a group formed by substituting a single bond between carbon atoms of the alkylene group with a bond selected from a group consisting of an ether bond, an ester bond and a phenylene bond, X represents a fluorine atom, a chlorine atom, a bromine atom or an iodine atom, and two R 1 's in the formula (I-2) may be the same as or different from each other and two R 3 's may be the same as or different from each other.

7 . A production method comprising:
reacting a compound including an isocyanate group that is not directly bonded to an aromatic ring in a molecule with a compound including an active hydrogen-containing group to produce a urethane compound, a thiourethane compound, an amide compound or a urea compound, wherein the reaction is performed in the presence of the reaction accelerator according to claim 1 .

8 . The reaction accelerator according to claim 2 , wherein the compound comprising an isocyanate group that is not directly bonded to an aromatic ring in a molecule is at least one selected from a group consisting of hexamethylene diisocyanate, trimethyl hexamethylene diisocyanate, lysine diisocyanate, norbornane diisocyanate, trans-cyclohexane-1,4-diisocyanate, isophorone diisocyanate, bis(isocyanate methyl)cyclohexane, dicyclohexylmethane diisocyanate, dimer acid diisocyanate, m-xylene diisocyanate, m-tetramethylxylene diisocyanate, other diisocyanate compounds represented by the general formula OCN—R—NCO (R represents a divalent aliphatic residue having 1 to 20 carbon atoms), methacroyl isocyanate, 3-isopropenyl-α,α-dimethylbenzyl isocyanate, 3-isocyanatepropyl trimethoxysilane, methacryloyloxyethyl isocyanate, acryloyloxyethyl isocyanate, 1,1-(bisacryloyloxymethyl)ethyl isocyanate, methacryloyloxyethoxyethyl isocyanate, acryloyloxyethoxyethyl isocyanate, and other monoisocyanate compounds represented by the general formula R″—NCO (R″ represents a monovalent aliphatic residue having 1 to 20 carbon atoms).
