ABSTRACT:
A surface treating agent for processing of metals, comprising (A) a water-soluble thermoplastic synthetic resin having a glass transition temperature of 60 to 90.degree. C and an average molecular weight of 15,000 to 50,000 which is obtained by copolymerizing (1) 16 to 40 parts by weight of an ester of acrylic acid with a monovalent aliphatic alcohol having 1 to 8 carbon atoms, (2) 40 to 64 parts by weight of a mixture of styrene and at least one of methyl methacrylate, vinyl acetate and acrylonitrile and (3) 10 to 20 parts by weight of a polymerizable monomer having a carboxyl group as the polar group, (B) a metallic soap and (C) water, said surface treating agent being able to be applied to a metal surface without heating to afford an unsticky coating film having excellent lubricating properties and excellent blocking resistance without accumulation on a press die in deep draw processing of the metal plate.
