Abstract: The invention is directed to a scratch ink composition improved in erasability, hiding power and ease of use. The invention relates to a scratch ink composition comprising a flaky pigment having a particle size distribution (as determined with a laser diffraction particle size distribution analyzer) such that the integral fraction of particles not larger than 10 &mgr;m in diameter is not more than 30%, a resin component, and a solvent.

Abstract: A junction box connector having a tubular body through which an electrical wire-carrying conduit is passed for termination at the junction box plate. The connector has an end which is designed to engage in an opening in the junction box plate, and may be locked in position so as to prevent axial pullout of the connector once it is in locked position, thus assuring electrical connection of the electrical wires in the junction box.
