Abstract:
1. A process for preparing roughened copper surfaces suitable for subsequent multilayer lamination, said process comprising the steps of: contacting with a clean copper surface an adhesion promoting composition under conditions effective to provide a roughened copper surface, said adhesion promoting composition comprising an oxidizer, a pH adjuster, and a topography modifier; and contacting said roughened copper surface with an acid resistance promoting composition having a formula selected from the group consisting of: wherein A is 1-20 and wherein X 1 is Mg, Ca, Li 2 , Na 2 , K 2 , or (NH 4 ) 2 ; wherein A is 1-20 and wherein X 1 is Mg, Ca, Li 2 , Na 2 , K 2 , or (NH 4 ) 2 ; and wherein W 1 is O—R 3 , or S—R 3 , wherein A is 1-20, wherein X 2 is Li, Na, K, NH 4 , wherein W 2 is O—R 6 , or S—R 6 , wherein B is 1-20, and wherein R 1-6 are independently selected from H and halogen, or wherein R 1-6 are independently selected from, or any two adjacent R 1-6 can be a linkage comprising S, epoxide, glycol, hydroxy, aryloxy, benzyloxy, alkoxy, haloalkoxy, amino, monoalkylamino, dialkylamino, heteroalkylamino, acyloxy, acyl, ketone, quinone, aldehyde, carbohydrate, organometallic, a C 1 up to C 18 alkyl which is linear or branched and may be singly or multiply substituted in singular or multiply bonded fashion, a cycloalkyl which may be singly or multiply substituted in singular or multiply bonded fashion, a heterocyclic which may be singly or multiply substituted in singular or multiply bonded fashion, a C 1 up to C 18 alkenyl which is linear or branched and may be singly or multiply substituted in singular or multiply bonded fashion, a C 1 up to C 18 alkadienyl which is linear or branched and may be singly or multiply substituted in singular or multiply bonded fashion, a C 1 up to C 18 alkynyl which is linear or branched and may be singly or multiply substituted in singular or multiply bonded fashion, an aryl which may be singly or multiply substituted in singular or multiply bonded fashion, a heteroaryl which may be singly or multiply substituted in singular or multiply bonded fashion, an alkylaryl which may be singly or multiply substituted in singular or multiply bonded fashion, an arylalkyl which may be singly or multiply substituted in singular or multiply bonded fashion, and combinations thereof, wherein the substituents are selected from the group consisting of halogen, epoxide, glycol, N, O, S, haloalkyl, hydroxy, aryloxy, benzyloxy, alkoxy, haloalkoxy, amino, monoalkylamino, dialkylamino, heteroalkylamino, acyloxy, acyl, ketone, quinone, aldehyde, carbohydrate, organometallic, alkyl, aryl, and combinations thereof.
