    摘要： A process for producing a curable resin liquid comprising: (a) at least one cyanate ester compound and (b) at least one polyfunctional maleimide compound, characterized in that the process comprises:(A) reacting at least one said maleimide compound with said diamine in the presence of a diluent at a temperature of 60.degree.-200.degree. C., the ratio of the maleimide group to the amine group being in the range of from 1:0.0015 to 1:0.3 to form a preliminary reaction product substantially free from amine group; and(B) mixing said preliminary reaction product with at least one cyanate ester compound ratio by weight of said preliminary reaction product to said cyanate ester compound is disclosed.
