Abstract
PURPOSE: The titled composition that is made by using a polyvinyl phenol or its halogenated product as a curing agent and an organic tin salt with a specific structure as a curing aid, thus having prolonged gelling time and giving cured product with high thermal resistance.
CONSTITUTION: To (A) an epoxy resin of 100W4,000 epoxy equivalent, are added (B) a poly-p-vinylphenol, preferably with a weight-average molecular weight of 3,000W8,000, and/or its halogenated product, so that the molar ratio of the epoxy groups in the component (A) to the active hydrogens in the component (B) becomes 0.5W2, and further (C) a tin salt of organic acid with at least one of linkage of the tin atom directly to an organic group, shown by formula I (R is monovalent organic group; R' is residue of organic acid; n is 1W3), formula II or formula III, so that the amount of the component (C) becomes 0.05W5pts./100pts. of the component (A).
USE: Prepleg for printing circuit base.
