Abstract
A curable composition is provided which comprises PA1 A. an imide group-containing compound which is either PA2 A. a bis-imide of the formula ##STR1## which D represents a radical of the formula ##STR2## in which Y represents H, CH.sub.3 or Cl, m is O or 1, and A represents a divalent organic radical containing 2 to 30 carbon atoms, or PA2 B. a mixture comprising a bis-imide of formula (I) and a mono-imide of the formula ##STR3## in which D is as defined above and R represents a hydrogen atom or a monovalent organic radical containing from 1 to 20 carbon atoms; and PA1 B. a polyurethane elastomer, in amounts such that the weight ratio ##EQU1## IS FROM 1/5 TO 4/1. Such compositions are useful for preparing moulded articles, adhesives, laminates and coatings.
