摘要:
Disclosed is a substrate for planographic (lithographic) plate, which comprises metal foils with thicknesses of 5 to 100.mu. laminated onto both surfaces of a sheet which has a thickness of 30 to 400.mu., said sheet being obtained by sheet making of a modified polyolefin composite material comprising 100 parts by weight of a modified polyolefin resin graft-modified partially or wholly with an organic silane compound and 5 to 150 parts by weight of mica.
摘要:
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.

Fibrous magnesium oxysulfate particles having a length of 10 to 100 .mu.m and a thickness of less than 1 .mu.m are used as an antiblocking agent for plastic films, especially polyolefin resin films.

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.
摘要:
A positioning system moves a movable element along a path and detects the movable element in a plurality of predetermined positions spaced along the path. The movable element is positioned selectively in the positions using a signal indicative of the detected movable element in the positions and a positioning command.
摘要:
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.
