Abstract: A printing sheet of the type which is used in a thermal transfer system, the printing sheet comprising a support and a dye receiving layer formed thereon, the dye receiving layer including a polymer containing isocyanate group, the polymer having polysiloxane unit and urea unit. The isocyanate group-containing polymer is selected from a reaction product between a multifunctional polyisocyanate compound and amino-modified silicone, or a reaction product between a multifunctional polyisocyanate compound and alcohol-modified silicone or carboxyl-modified silicone and an amine compound or water. According to the present invention, both the writing characteristic and anti-sebaceous characteristic on an image surface are improved simultaneously while basic characteristics such as printing sheet sensitivity, image preservative stability, and so on, are satisfied.

Abstract: An image receiving sheet for thermal transfer printing according to the present invention comprises a dye receiving layer, a foam film, an adhesive layer, a release layer, a support layer and a lubricant layer which are successively laminated. The image receiving sheet for thermal transfer printing has a seal portion consisting of the dye receiving layer, the foam film and the adhesion layer, also having a support portion consisting of the release layer, the support layer and the lubricant layer. The image receiving sheet for thermal transfer printing according to the present invention is formed such that:(1) smoothness of the dye receiving layer is equal to or larger than 2000 seconds;(2) the foam film contains a white inorganic pigment of 5 to 30 weight % and a micro void formed by mixing resins that are not compatible with each other, having a cushion ratio of 5 to 30% and a density of 0.7 to 1.1 g/cm.sup.

Abstract: A thermal transfer dye image-receiving sheet resistive to fuse-adhesion of ink ribbons and to dye-adhesion at a back surface thereof, comprising a dye-receiving layer formed on a front surface of a substrate sheet and comprising a dye-receiving resin material, for example, a polyester, and a back surface coating layer formed on a back surface of the substrate sheet and comprising a release agent comprising at least one member selected from silicone block copolymer resins, silicone oils, silicone varnishes, fluorine compounds, phosphate compounds or fatty acid ester compounds.

Abstract: A thermal transfer dye-image-receiving sheet useful for producing clear dye images having a high evenness in color density, includes a resin coating layer formed on at least one surface of a substrate paper sheet, comprising a thermoplastic resin, for example, polyolefin, and having a modulus of elasticity in flexure of less than 7,000 kg/cm.sup.2 as determined in accordance with Japanese Industrial Standard K 7203, and a dye-image-receiving layer formed on the resin-coating layer and comprising a dye-receiving resin.

Abstract: The invention relates to carbonaceous bricks having resistance to fire and corrosion, capable of withstanding mechanical impact to which the conventional carbonaceous bricks were vulnerable, and usable in an oxidizing atmosphere, and the method as producing the same. The invention has for an object to obtain carbonaceous bricks having said high properties by mixing less than 60 weight % of inorganic material with 40.about.100 weight % of pellets consisting of carbonaceous material containing substantially more than 70 weight % of carbon and a bonding agent comprising pulverized phenol resin, liquid thermosetting resin and/or setting accelerator, bricks formed therefrom containing more than 40 weight % of carbon.

Abstract: A fire brick unit or assembly is proposed which has a pile of fire bricks laid one upon another on a supporting member to facilitate the building and dismantling of industrial furnaces. It further includes suspending members on which can be lifted with a crane or the like. There is no necessity of laying or removing fire bricks one by one.

Abstract: A composite brick is proposed which is produced by integrally molding two kinds of bodies, a magnesia-carbonaceous refractory and a basic refractory. These two bodies are put into respective positions in a metal case partitioned by a plate and subjected to pressure molding into a compact brick unit. This composite brick is much less expensive than the conventional high-purity magnesia-carbonaceous bricks. This means a substantial saving in the manufacturing cost of a furnace.
