PURPOSE: The titled composition that is obtained by adding 1,3,5-tris(4-t-butyl-3- hydroxy-2,6-dimethylbenzyl)isocyanuric acid to a copper-containing paint, thus showing resistivity stabilized for a long period of time, even under heating or moisture-absorbing conditions, because the copper is prevented from being oxidized. n CONSTITUTION: The objective composition is obtained by combining (A) 100pts.wt. of a thermoplastic resin such as acrylic resin or vinyl resin and/or a thermosetting resin such as unsaturated polyester resin or epoxy resin with (B) 50W2,000pts.wt. per 100pts.wt. of A of copper powder, preferably of higher than 99% purity and less than 50μ particle sizes and (C) 0.01 or more, per 100pts.wt. of components A+B, of 1,3,5-tris(4-t-butyl-3-hydroxy-2,6-dimethylbenzyl)isocyanuric acid, to give the objective composition. n EFFECT: The composition is free from change in electric resistance with low resistivity. n COPYRIGHT: (C)1984,JPO&Japio |
