    摘要： The present invention provides a halogen-containing cyanate ester obtained by cyanating a phenol represented by the following general formula (1):
    wherein A represents a hydrocarbon group having 1 to 6 carbon atoms; B represents a halogen atom; X represents a single bond, a hydrocarbon group having 1 to 20 carbon atoms, a carbonyl group, a sulfon group, a divalent sulfur atom or an oxygen atom; i represents an integer of 0 to 3; j represents an integer of 1 to 4; and n is 0 or 1 with a cyanogen halide in the presence of and a base, wherein a value obtained by dividing a maximum value of an absorbance at a wave number of 1600 to 1740 cm -1 by a maximum value of an absorbance at a wave number of 2100 to 2300 cm -1 is not more than 0.2, the absorbance of a 1.0 % (weight by volume) chloroform solution of the halogen-containing cyanate esters being measured at a cell length of 1.0 mm using an infrared spectrophotometer.
    The present invention also provide a process for producing the same, and a thermosetting resin containing the same.
