ABSTRACT:
In pressing and molding a shadow mask or the like, press-molding oil containing alkyl carbonate shown in the following Chemical Formula as an active ingredient is coated on a press mold. After pressing and molding a metallic material with the press mold, the press-molding oil is washed and removed with warm water. Alternatively, the oil is dried or thermally decomposed. As a result, less than about 10 .mu.g/cm.sup.2 oil is left as residue on the product. ##STR1## where a and b are an integer from one to six; x and y are an integer from 0 to 30; R.sup.1 and R.sup.2 are an alkyl group, cycloalkyl group, alkylphenyl group, benzyl group or alkylbenzyl group having from one to thirty carbon atoms and straight or branched alkyl chains.
