Abstract

PURPOSE: To provide titled compsn. which is useful for varnish, excels in curing characteristics and produces flame-retardant cured articles, consisting of a specified polyvalent maleimide cpd. and a polyhydric phenol having at least two hydroxyl gp. in the molecule.
CONSTITUTION: (a) A polyvalent maleimide cpd. of the formula (produced by a method wherein an amic acid resulting from the reaction of maleic anhydride with aniline-formaldehyde condensate is subjected to a dehydrating reaction to form an imide ring) is blended with (b) a polyhydric phenol having at least two hydroxyl gp. in the molecule (obtd. by reacting a phenol such as phenol, o-cresol, or bisphenol A with formalin or formaldehyde in the presence of a catalyst) in such a proportion as to give 30W70wt% of (b) component based on the total weight of compsn., to obtain titled compsn.
