Claims
- 1. A composition comprising a polyamine and a melamine aldehyde acid colloid polymer in a ratio of about 90.0-99.9 parts by weight polyamine to about 10.0-0.1 parts by weight of acid colloid polymer; wherein said polyamine has a molecular weight ranging from about 25,000 to about 1 million and is a reaction product of a secondary amine and a difunctional epoxy compound or precursor thereof; wherein said melamine aldehyde acid colloid polymer has a molecular weight ranging from about 500 to about 200,000.
- 2. A composition according to claim 1 wherein the ratio of said polyamine to said acid colloid polymer ranges from about 96.5-99.1 parts by weight polyamine to about 3.5-0.1 parts by weight acid colloid polymer.
- 3. A composition according to claim 1 wherein said polyamine has a molecular weight ranging from about 50,000 to about 1 million.
- 4. A composition according to claim 1 wherein said polyamine is a reaction product of a dimethylamine and an epihalohydrin or precursor for epihalohydrin.
