A process for preparing a uniaxial polyester film which comprises: a) extruding a moving molten web of polyester film; and b) quenching the moving web to solidify it in a substantially amorphous form; and c) applying a coating of a dispersed aqueous composition of polyvinyl alcohol or polyurethane to at least a portion of the surface of said film; and d) stretching the moving web in a direction t...

PURPOSE:To uniformlly monolithically unite a surface of a polymer with an acryl film, by a method wherein a specified acryl series film composite product having a carrier film is laminated on a semipolymer surface to polymerize and cure it, and the carrier film is peeled for removal. CONSTITUTION:A polyalkylmethacrylate series film is laminated on a carrier film, not dissolved in a polymerizable m...

There is prepared a homogeneous mixture of 95 to 30% carbon black and 5 to 70% resorcinol. The resorcinol preferably either has an average particle size of 0.10 to 0.4 0.40 mm or is broken down to that size. The product is employed in rubber mixture to improve the adhesion of rubber vulcanizates to metal, textile fibers, glass fibers, or their structures.

1. Method for producing fibre-reinforced flat bodies, wherein a water containing flowable core layer is introduced between a substrate layer and a cover layer, characterized in that the three layers of which at least one of the outer layers comprises actively needle bondable fibres, are bonded together in the water containing state by needling so that the layers have coherence in a deformable stat...

PURPOSE:To improve the stability and reliability of a recording unit by such an arrangement wherein an ink current is accelerated and stabilized by causing it to fly together with air current supplied from an air supply source, by this arrangement, the rise time and fall time of air pressure at the time of starting and stopping of the air supply source are made to be variable. CONSTITUTION:By clos...
