Abstract: An image is provided by depositing a first layer of a photoresist containing a phenolic-formaldehyde novolak type polymer and an imidazole, benzimidazole, triazole, or indazoles to increase the solubility of the layer in aqueous alkaline developer after exposure to imaging radiation; depositing on the first layer a second layer of a photoresist containing a phenolic-formaldehyde novolak type polymer; the second layer having a lower degree of solubility in aqueous alkaline developer after exposure to imaging radiation; exposing the layers to imaging radiation; and developing the layers.
