  • Patent number: 5472792
    Abstract: A laminated film has layer(s) A and layer(s) B.sub.1, obtained by laminating at least one layer A and at least one layer B.sub.1. The layer A comprises a resin composition comprising (a) 20-100% by weight of an amorphous polyolefin containing at least one component, in an amount of at least 50% by weight in said amorphous polyolefin, selected from the group consisting of propylene and butene-1 and (b) 80-0% by weight of a crystalline polypropylene, (B) the layer B.sub.1 comprises a crystalline polypropylene. At least one of the two outermost layer is the layer B.sub.1. The laminated films can be used in various applications by themselves, but may be laminated with a polyester film, a nylon film, a stretched polypropylene film or the like to improve the mechanical strengths, gas-barrier property, printability, etc.

  • Patent number: 4327148
    Abstract: A self-contained color forming pressure sensitive record paper of the single coating type which has on one side of a support a coating layer of a mixture of color former-containing microcapsules and color developer-containing microcapsules, as well as a powdered polyolefin. The powdered polyolefin acts as capsule protecting agent and prevents the smudging due to unintentional color development caused by the rapture of the capsules.
