摘要:
Disclosed is a resin composition for heat-sensitive transfer recording medium, comprising (A) a silicone resin and (B) at least one resin selected from the group consisting of polyester resins, polyamide resins, cellulose type resins and acrylic resins.Disclosed is also a heat-sensitive transfer recording medium having at least one colorant layer containing a heat-fusible substance on a support, comprising a backing layer formed from (A) a silicone resin and (B) at least one resin selected from the group consisting of polyester resins, polyamide resins, cellulose type resins and acrylic resins provided on the surface of the support where no colorant layer is provided.The resin composition for heat-sensitive transfer recording medium of the present invention has sufficient heat resistance.Also, the heat-sensitive transfer recording medium utilizing the resin composition for heat-sensitive transfer recording medium as a backing layer is free from generation of blocking phenomenon between the backing layer and a colorant layer even when stored for a long term under wound state, contamination of thermal head, generation of sticking phenomenon, transfer irregularity of a colorant layer and printed image defect.

摘要:
A heat-transfer recording medium is disclosed, which produces no lowering in transfer density even when the medium is used under such higher-temperature conditions as in a facsimile equipment and is capable of providing an easily readable transferred image having a low surface gloss, as well as having an excellent keep-secrecy and producing few voids. The recording medium comprises a support; a heat-transfer layer, provided on the support, comprising a thermo-fusible substance and a colorant; and a non-transfer layer which is interposed between the support and the transfer layer and comprises a colorant, a thermoplastic polymer selected from the following Group A and a thermoplastic polymer selected from the following Group B:Group A: an .alpha.-olefin polymer, an .alpha.-olefin-maleic anhydride copolymer, an .alpha.-olefin-alkyl acrylate and methacrylate copolymer, an .alpha.-olefin-vinyl acetate copolymer, an .alpha.-olefin-acrylic or methacrylic acid copolymer, a vinyl acetate polymer, an alkyl acrylate or methacrylate polymer, a acrylic or methacrylic acid polymer and a styrene-containing polymer;Group B: A polyester resin, a polyurethane resin, a polyvinyl chloride resin and an epoxy resin.

摘要:
The present invention provides a guidewire having a reduced diameter, which ensures rigidity and excellent guidance ability in spite of its reduced diameter, and which achieves an excellent sliding ability and insertion/pulling-out ability with respect to a catheter or the like. The guidewire has an inner core formed of a single wire having an uneven surface on its outer circumferential surface, a high-polymer coating which densely covers the outer circumferential surface of the inner core, and an uneven surface formed on the outer circumferential surface of the high-polymer coating by an influence from the uneven surface on the outer circumferential surface of the inner core.
