    摘要: In accordance with the present invention, a method of treating the surface of an organic substrate, particularly a circuitized surface of an organic substrate, which method reduces the spread of adhesive resin that is subsequently deposited on the surface, is provided. This method comprises the steps of applying a treatment solution comprising a fatty acid compound, an alkalizing agent, and a solvent comprising water and from about 5% to about 90% by volume of an organic solvent selected from the group consisting of an alcohol, a glycol ether, and combinations thereof to the surface; and then removing substantially all of the solvent from the solution to provide a thin film on the surface of said substrate. The film comprises the fatty acids that were present in the treatment solution. In a preferred embodiment the treatment solution further comprises a chelating agent. The present invention also relates to a treatment solution for reducing adhesive resin bleed on the surface of a circuitized organic substrate. The present invention also relates to a circuitized organic substrate that is resistant to resin bleed. Such substrate has a film comprising a fatty acid compound disposed on the circuitized surface thereto.
