Abstract

There is provided a curable composition comprising one or more reactive components that cure upon exposure to suitable conditions, the curable composition comprising:
(i) at least one aromatic nitroso or at least one aromatic nitroso precursor compound or combinations thereof; and (ii) a film former component comprising at least one non-halogenated hydroxy group-containing resin together with at least one crosslinking agent.

First claim

1 . A curable composition comprising one or more reactive components that cure upon exposure to suitable conditions, the curable composition comprising:
(i) at least one aromatic nitroso or at least one aromatic nitroso precursor compound or combinations thereof; and (ii) a film former component comprising at least one non-halogenated hydroxy group-containing resin together with at least one crosslinking agent.

2 . The curable composition of claim 1 wherein the at least one non-halogenated hydroxyl group-containing resin includes a co-polymer which is a co-polymer of at least one of polyvinyl alcohol, polyvinyl butyral and polycellulose acetate butyrate, wherein said co-polymer is a block co-polymer and the non-halogenated hydroxyl group-containing resin has the general structure:

wherein each of n, o and p is at least 5, and the combined % wt of the m, o and p components in the non-halogenated hydroxyl group-containing resin is 100%.
