PURPOSE:A synthetic resin composition that is obtained by adding an inorganic filler having hydroxyls bonding to metals of group IIa or IIIb in the periodic table, thus showing good stamping properties when it is carved with heat at high temperatures, especially with laser beams. CONSTITUTION:The objective composition is obtained by adding, to a synthetic resin, more than 1wt%, preferably more than 5wt% of a substance, preferably in the fine particle form, selected from inorganic fillers bearing hydroxyls bonding to metals of group IIIa or IIIb in the periodic table, hydrates aluminum-silicon salts such as talc, hydrated silicates such as amphibole, hydroxides of metals of group IIa and IIIb, preferably caolinite or aluminum hydroxide. The resultant composition is formed into articles to be directly stamped or made into a liquid or powder coating, which is applied to the substrates to be stamped or made into a laminate, which is adhered to parts to be stamped.
