New photoresist compositions are provided that comprise a component that comprises an amide group and multiple hydroxyl groups. Preferred photoresists of the invention may comprise a resin with photoacid-labile groups; a photoacid generator compound; and an amide component with multiple hydroxyl groups that can function to decrease undesired photogenerated-acid diffusion out of unexposed regions of a photoresist coating layer.

Methods and compositions are provided for heat treating, e.g. quenching a metal. The quenching composition includes a composition that comprises a polyamidopolyamine compound having a molecular weight of about 500 to about 100,000 and comprising a pendent amino group; and/or a non-polymeric amidoamine having a molecular weight of about 290 to about 5000 and comprising an amino group; and a hydroxyl containing diluent. These compositions impart one or more of the functions of quenching, lubricity, anti/low foaming and/or bioresistance to the quenching fluid.

Compositions comprising a polyamidopolyamine and/or a non-poly-meric amidoamine are disclosed for imparting multiple desired characteristics to a variety of industrial compositions. In certain embodiments, these compositions are prepared by condensing a C.sub.4 to C.sub.16 poly basic acid, monobasic acid or derivative thereof with a polyamine comprising a primary amino group, and in the presence of an optional organic diluent. Certain specific polyamidopolyamine and a non-polymeric amidoamine formulae and compositions containing same are disclosed, as are methods of use of these compositions.
