ABSTRACT:
A process is disclosed for treating cellulose ester articles which comprises applying to the surface of the articles a solution of alkylated melamine such as hexamethoxymethylmelamine and an acid catalyst. The solution is applied such as to result in a deposit of alkylated melamine in an amount of between about 1% and about 10% based on the weight of the cellulose ester article and acid in an amount of from about 0.01 to about 1.0% based on the weight of the cellulose ester article. The article is then heated to cause a reaction to occur between the alkylated melamine and the surface of the cellulose ester article to form a crosslinked skin to render the article resistant to attack by solvents.
