An electrically-conductive resin composition comprises (A) a thermoplastic resin and (B) an electrically-conductive polymer blended together. The electrically-conductive polymer is an electrically-conductive polyester doped with a dissociable inorganic salt. The doped polyester is at least one polyester selected from the group consisting of (a) polyesters each of which has a weight average molecular weight of from 50,000 to 500,000 and has been obtained by subjecting at least caprolactone as a monomer to ring-opening polymerization and (b) comb polyesters each of which has one or more polyester chains each having a weight average molecular weight of from 50,000 to 200,000 and has been obtained by subjecting a lactone to ring-opening polymerization in the presence of a trifunctional or higher functional, polyhydric alcohol as a polymerization initiator. Electrically-conductive resin moldings made of such electrically-conductive resin compositions are also disclosed.

Electrically-conductive resin compositions and moldings

A heat-sensitive recording medium is composed of a base sheet, a heat-sensitive recording layer provided on one side of the base sheet and a heat-resistant layer provided on the other side of the base sheet. The heat-resistant layer is made of a resin containing siloxane bonds in its molecule.

Heat-sensitive recording medium

A thermosettable polyurethane product is prepared by blending a compound having two or more terminal isocyanate groups to a thermoplastic resin which is inert to said isocyanate group to prepare an isocyanate compound batch, and further blending the isocyanate compound batch to a thermoplastic polyurethane resin and fabricating the resulting mixture.
