Abstract: PURPOSE:To form an image having excellent steadiness and clearness by making a ribbon cassette, which is to be used for a tape printer, of a thermal transfer ribbon, a temporary transfer ribbon for temporarily transferring the image from the thermal transfer ribbon, and a cloth ribbon for transferring the image from the ribbon. CONSTITUTION:A cloth-containing ribbon cassette 1 for thermal transfer is made of a set of a cloth ribbon 2, a thermal transfer ribbon 3 and a temporary transfer ribbon 4. In printing images, the ribbon cassette 1 is set in a printer, a temporary image is transferred to the temporary transfer ribbon 4 from the thermal transfer ribbon 3 by a print head 5 built in the printer, and the cloth ribbon 2 is layered thereon so as to obtain a laminated label 7. In the laminated label 7, an image 12 is formed by a dye-containing ink on a temporary transfer sheet 11, and a cloth 13 is layered thereon. The laminated label 7 is pressed with heat by an iron at 180-200 deg.C. Thereafter, the temporary transfer ribbon 4 is treated to be peeled off, thereby obtaining a cloth label.

Abstract: PURPOSE:To form an image having excellent fastness, vividness and so forth by constituting a ribbon cassette of a cloth ribbon roll, an excessive dye elimination ribbon roll and a thermal transfer ribbon roll with a dye impregnated thermal transfer layer. CONSTITUTION:The transfer cloth insertion ribbon cassette is composed at least of a cloth ribbon roll, excessive dye elimination ribbon roll, and thermal transfer ribbon roll having a thermal transfer layer consisting of dye-containing ink. Concretely, it has an image 12 formed by dye-containing in the cloth 13 and further an excessive dye elimination sheet 11 laminated thereon. By heating the lamination body label and separating the excessive dye elimination sheet 11, there is obtained a cloth label dyed with an image 12. Since the cloth label obtained has a dye image, it has a very fine fastness such as a friction resistance, washing resistance and the like. The provision of a hot melt adhesive layer to the rear surface of the cloth label allows dyeing and simultaneously adhering to clothing or the like.

Abstract: PURPOSE:To obtain a ultrahigh air-containing and highly self-stretchable string- form object having a stable structure after self-stretching by a method wherein a laminate is composed of a low-temperature shrinking sheet layer, a high- temperature shrinking sheet layer, and two types of adhesive layers. CONSTITUTION:A low-temperature shrinking sheet 1 and a high-temperature shrinking sheet 2 are bonded by adhesive layers 3 and 4 to be laminated, thereby being formed into a string-form object. As the low-temperature shrinking sheet 1, paper of 100mum thickness is used. As the high-temperature shrinking sheet 2, a vinyl chloride shrink film (40mum thick and having a shrinkage factor of 50% laterally and 0% vertically) is used. As the adhesive layers 3, 4, an epoxy adhesive is separately used. The paper and the vinyl chloride shrink film is 10mm long and 20mm wide. The three-layer paper/shrink film/paper laminate bonded through the adhesive layers of 2mm width at both ends is laminated by 16 layers through the adhesive layers of 5mm width at the center.

Abstract: PURPOSE:To enable a long time of display via the use of the optical characteristic of high molecular gel to be realized, and reduce heat generation and consumption power by providing a stimulus transmission mechanism to stimulate a specific high molecular gel. CONSTITUTION:This display board is constituted of a gel section 1 comprising a high molecular gel molding of stimulus responsive and optical modulation type, and a stimulus transmission mechanism to stimulate the gel 1. In this case, the gel section 1 may be a substance having optical characteristics including transmittance, reflectance and a refraction factor capable of reversible function due to an environmental change, such as a change in temperature, solvent composition, pH value and ion composition, or electricity, magnetism, electric field, magnetic field, light radiation or the combination thereof. Practically, however, a preferable substance is such as capable of reversible function due to an environmental change comprising a combination containing at least one of electricity, magnetism, electric field and magnetic field. The high molecular gel 1 is enclosed with a black plastic 2, and this plastic 2 is clamped with transparent conductive films 3 and 3' at the upper and lower sides. Voltage is applied across the films 3 and 3', thereby changing the transparency of the gel 1.
