Gel formation is prevented in the reaction between a
sulfonyl-chloride-containing resin and a polyamine by first forming an
adduct between the resin with an aminophenol. The prevention of gel
formation enables sulfonyl-chloride containing resin to be used in
admixture with acrylates and epoxy resin to form a polyamine-curable
adhesive composition having excellent adhesive properties and chemical
resistance.
