  • Publication number: 20110143157
    Abstract: Disclosed are an aqueous adhesive composition for dry lamination and a laminate fabricated using the same. More particularly, the disclosed aqueous adhesive composition for dry lamination includes an aqueous resin dispersion A and a water-dispersible isocyanate B, wherein the aqueous resin dispersion A is prepared using the following ingredients (a) to (d), that is, an unsaturated monomer having a hydroxyl group (b), C1-C4 alkyl acrylic and/or methacrylic ester (c) and an additional unsaturated monomer (d) co-polymerizable with the unsaturated monomer (a), in the presence of an emulsifier having a phosphate group (a). The aqueous adhesive composition for dry lamination as described above exhibits excellent adhesion when used in laminate adhesion between at least two different plastic films, a plastic film and an aluminum foil or a metal welding film, etc., while having superior hydrothermal resistance sufficient for a resulting laminate to endure hot water conditions.

  • Patent number: 5860523
    Abstract: A tape cassette receiving housing comprises a housing proper portion and a lid portion which is fixed to the housing proper portion through a hinge portion so as to enable to be opened or closed. Shaft portions are formed so as to penetrate into reel driving holes of a supply reel and a take-up reel of a tape cassette received in the housing proper portion. Elastic bodies are attached to outer peripheries of the shaft portions, and the elastic bodies are brought into contact with inner peripheral surfaces of reel driving holes. According to the above construction, a tape cassette is fixed in the tape cassette receiving housing so as not to incline the tape cassette and not to rotate the supply reel and the take-up reel.

  • Patent number: 5474249
    Abstract: A tape cassette is provided which has indicia indicating the characteristics of the tape contained therein. In one embodiment an information discriminating mark, capable of being optically sensed is provided on the magnetic tape. Fluctuations in the transmittance of the tape are detected by a photodetector device and a difference in the detected output is utilized for identifying the type of the tape cassette. In another embodiment, the bottom surface of the tape cassette is provided with physical indicia indicating the characteristics of the tape contained therein.

  • Patent number: 5239436
    Abstract: An improved tape cartridge with increased tape capacity comprises a cartidge housing including a base plate which has two portions. The two portions connect with each other to form at least one corner portion. At least one guide is located adjacent the one corner portion such that the tape web is held out of interference with the one corner portion. A driven roller is positioned such that a straight line drawn through the driven roller passes between axes of rotation of two tape packs mounted on the base plate and extends perpendicular with a straight line extending through the axes of rotation of the tape packs.

  • Patent number: 4916006
    Abstract: A heat-sensitive transfer recording material for use in a heat-sensitive transfer recording means such as a thermal printer is provided. The recording material comprises a heat-sensitive transfer ribbon having a heat-fusible ink layer provided on the surface of a polyester base film and a heat-resistant protective layer. The heat-resistant protective layer comprises (1) a chlorinated product of a 4-methyl-1-pentene polymer or a derivative thereof and an amorphous linear saturated polyester or (2) at least one member selected from the group consisting of chlorinated products of acid-modified 4-methyl-1-pentene polymers and acid-modified 4-methyl-1-pentent/.alpha.-olefin copolymers.

  • Patent number: 4131717
    Abstract: A magnetic recording medium including a non-magnetic base and a magnetic layer thereon which contains and/or is coated with an organopolysiloxane having an average unit with the formula: exhibits(CH.sub.3)(RO).sub.n (R'COO).sub.m SiO.sub.(3-n-m)/2wherein R is a monovalent hydrocarbon group having from 1 to 5 carbon atoms, R' is an aliphatic monovalent hydrocarbon group having from 7 to 17 carbon atoms; n is zero or a positive number, m is a positive number with the proviso that n + m is less than 3 and the number of Si atoms in a molecule of such organopolysiloxane ranges from 2 to 8. Magnetic recording medium containing such organopolysiloxane material exhibit a substantially reduced dynamic friction coefficient and a substantially reduced tendency of the magnetic layer to lose magnetic particles, along with an improved splicing-ability.
