    Abstract: A thermal transfer recording medium is disclosed which is improved not only in the print quality on a transferee medium of poor smoothness, but also in character quality in a high speed printing operation. The recording medium comprises a support and at least two heat softening layers provided on the support in the order of a first heat softening layer and a second heat softening layer. At least one of said first and second heat softening layers contain a colorant, and said second heat softening layer contains a heat fusible substance in an amount of from 15% to 50% by weight; a thermo-plastic resin in an amount of from 20% to 80% by weight; and a tackifier in an amount of from 5% to 35% by weight.

  • Patent number: 4791024
    Abstract: To provide a selective and repetitive junction system by adhesion of separate parts an adhesive element is suggested which is capable of being jointed only with another identical or similar element, which comprises a carrier and an adhesive layer on at least one side of the carrier, said layer being composed by an elastomeric material firmly anchored to the carrier. The layer is preferably rather thin and smooth.

  • Patent number: 4690848
    Abstract: Weather-resistant boards are provided herein which are possessed of surface elasticity and pliancy by means of a permanently elastic, covering layer (for example, particle boards, facade covering boards, and wall elements) and mouldings (for instance, containers, vessels, prefabricated building elements, and roof elements), the base material being lignocellulose or other organic materials and/or inorganic materials, either as fibres or as particle materials. Such weather resistant boards consist of three layers. The first layer is an impregnatable porous, base material as defined above. The second layer is a vulcanized outer covering layer constituted by an vulcanized, weather-resistant resilient synthetic elastomeric material which has been vulcanized therein in situ at a temperature of at least 175.degree. C.

  • Patent number: 4663224
    Abstract: A composite board having an excellent vibration-suppressing sound-shielding performance can be obtained by joining a plurality of board materials with each other by the intermediary of a tacky adhesive. This tacky adhesive contains, as its principal components, one or more kinds of polymers selected from the group consisting of natural rubber, synthetic rubbers, various resins (acrylic resin, silicone resin, etc.). A sheet-like base material such as a paper sheet can be used in association with the tacky adhesive layer in the composite board, and such type of composite boards have an excellent vibration-suppressing sound-shielding performance as compared to the composite boards in which the tacky adhesive layer is not associated with a sheet-like material.

  • Patent number: 4601925
    Abstract: The invention relates to a cushion for use on top of a hard paving material in a race track or playing field and comprises three rubber coated coconut husk fiber bodies superimposed on each other. The fibrous bodies are adhesively bonded to each other by rubber adhesive and the middle layer has the coconut fibers compressed to a lesser extent than the compression of the fibers in the upper and lower layers.

  • Patent number: 4562103
    Abstract: Weather-resistant boards possessed of surface elasticity and pliancy by means of a permanently elastic, covering layer (for instance, particle boards, facade covering boards, and wall elements) and mouldings (for instance, containers, vessels, prefabricated building elements, and roof elements) of resin-impregnated wood fibres or other organic materials and inorganic materials, either as fibres or as particle materials are provided herein. Such weather resistant board comprises three layers. The first layer is an impregnatable, porous, base material which is constituted by a mixture of a curable resin with an organic base material, namely a lignocellulose fibrous or particle material, and an inorganic mineral fibrous material. The second layer is an outside elastic covering layer constituted by a vulcanized, weather-resistant resilient synthetic elastomeric material vulcanized thereon in situ at a temperature of at least 175.degree. C.

  • Patent number: 4394416
    Abstract: Disclosed is a film-paper fiber layer laminate comprising a film and a very thin paper fiber layer bonded to the surface of the film. This laminate is prepared by bonding films to both surfaces of a paper so that the adhesive bond strength between the film and the paper is higher than the failure strength of the paper fiber layer and separating the films by delamination. This film-paper fiber layer laminate is excellent in the transparency and dimension stability, and the tearing strength of the film per se is completely retained and the laminate is suitably used as a tracing paper.
