  • Publication number: 20240104321
    Abstract: A printing system includes: a communication interface that acquires printing data from a device; a first printing mechanism that performs printing on a first medium; a second printing mechanism that performs printing on a second medium; and a processor that analyzes an image of the acquired printing data, permits printing on the first medium and printing on the second medium when it is determined that the image of the printing data is a first type image, and permits printing on the first medium and prohibits printing on the second medium when it is determined that the image of the printing data is a second type image.

  • Patent number: 5910356
    Abstract: An adherent polyester film laminate (A) having a coating layer of a composition formed on one side or both sides of a polyester film, the composition comprising, as main components, (i) an aqueous polyester having a secondary transition point of 40 to 85.degree. C. and (ii) a fatty acid bisamide; a polyester film laminate (B) having a hard coat layer formed on the coating layer of the laminate (A); and a polyester film laminate (C) having an anti-reflection layer formed on the hard coat layer of the laminate (B). Since these laminates are excellent in adhesive force, transparency and slipperiness and has an anti-reflection property, they are useful as a face surface protective material for glass and displays.

  • Patent number: 5908688
    Abstract: An antistatic polyester film having formed on at least one side of a polyester film a coating layer which consists essentially of (a) 5 to 40% by weight of a phosphoric acid ester salt-based antistatic agent, (b) 1 to 20% by weight of a surfactant having an HLB value of 12 or less, (c) 40 to 90% by weight of at least one binder selected from acrylic copolymers and polyester copolymers, and (d) 3 to 25% by weight of fine particles having an average particle diameter of 10 to 500 nm and which has an extremely uniform surface. This film is excellent in anti-blocking properties at a high humidity and antistatic properties at a low humidity.

  • Patent number: 5294592
    Abstract: A thermal-transfer recording sheet of an aromatic polyester film, wherein at least one surface of said sheet has, as a thermal-transfer ink receiving layer, a coating of a composition comprising (1) a copolyester, (2) a polyolefin fine particle filler and (3) an antistatic compound selected from the group consisting of organic titanate and organic zirconate. The above thermal-transfer recording sheet exhibits excellent adhesion to heat-melting inks and excellent capability of receiving heat-melting ink layers and has good antistatic properties.
