A substrate is bonded to a polymeric material based on a plastics material on an elastomeric block copolymer according to DT. P1908810.9 and present modification consists of contacting teh substrate with a polymeric cpd. in presence of (A) a polyhydroxy compd. of formula: and (II) which is as in (I), with a further bridging radical of formula: between and ring B. R1-14 cam be H, OH, alkyl, allyl, aryl, or aralkyl gp and at least one of R1-5 and at least one of R6-10 is OH Further, at least one H atom is o- or p- to the OH gps. in both rings, and (B) a cpd. capable of reacting with (A) to form an aldehyde condensation resin, followed by heating to effect curing.
