PURPOSE:To obtain the subject composition containing a specific esterified product, etc., and a specific polyvinylpyrrolidone at a specific portion, and imparting excellent formability, lubricity, joining property and adhesiveness to a metal thin plate applied with the composition which is useful for plastic processing. CONSTITUTION:The objective composition contains (A) an esterified product obtained by esterifying a copolymer of monomer component mainly containing maleic acids and styrenes in a molar ratio of (1/99) to (75/25) with one or two or more kinds of hydroxyl group-containing compounds having >=10wt.% 4-30C alkyl group or alkenyl group, e.g. an aliphatic alcohol epoxide adduct in >=5 equivalent% esterification ratio based on a carboxyl group in the copolymer and/or its salt and (B) a polyvinylpyrrolidone having >=10000 weight average molecular weight in (10/90) to (95/5) weight ratio of the components A/B. Furthermore, the composition is applied to the surface of a metal thin plate to provide the objective lubrication-treated metal thin plate. |
