Abstract: A self-supporting sheet-like structure is described, which contains a substrate layer and a structured coating on at least one surface of the substrate layer. The structured coating is produced by treating at least one surface of the substrate layer by means of an electric corona discharge, which takes place between a high voltage electrode and a grounded counter-electrode. In this procedure, an aerosol containing discrete inert particles is simultaneously introduced into the corona discharge space during the corona discharge to improve the slip characteristics and reduce friction of the substrate layer.

Abstract: A polymeric film comprises a substrate layer of polymeric material and a coating layer formed from a composition comprising a layer mineral and a cross-linking agent. The coating layer comprises greater than 10% and less than 90% by weight of the layer of the layer mineral and greater than 10% and less than 90% by weight of the layer of a resin derived from the cross-linking agent. The coating layer preferably additionally comprises a copolymer of ethylene with a vinyl monomer. The polymeric film can have oxygen barrier properties, and the layer mineral coating layer exhibits improved adhesion to the polymeric substrate. The polymeric film is particularly suitable for use as a packaging film.

Abstract: A process for producing an apertured nonwoven fabric combines one or two outer nonwoven layer(s) with a layer of polymeric material having a lower melting temperature and a property of shrinking when melted. Heat and pressure are applied through a calendar roll such that the polymeric material becomes bonded to the fibers of the nonwoven layer(s) and simultaneously shrinks and takes back the fibers away from the calendaring points, thereby generating apertures through the nonwoven fabric. Preferably, the fibers are polyethylene or polypropylene fibers, and the layer of polymeric material is a thin plastic film of polyethylene stretch-wrap, elastomeric, or heat shrink material. One outer nonwoven layer may be combined with the plastic film layer to form a bi-laminate product, or two outer nonwoven layers may be combined with an intermediate plastic film to form a tri-laminate product. Low denier polypropylene/polyethylene bi-component fibers or a blend of higher and lower melting fibers may also be used.

Abstract: An improved insulation package for insulating objects and method of making the same are disclosed. The insulation package comprises one or more layers of insulation material closed within a loose fitting cover. The cover is easily fitted around the pieces of insulation material. The insulation package saves time and labor compared to the previous method of prefabricating individual covers for each shape of insulation material. In a preferred embodiment, the cover can be formed of any of the following: water proof materials, water resistant materials, air permeable materials and combinations thereof.

Abstract: The invention provides a multi-layer film having 1 to 4 polyamide layers, characterized in that at least one polyamide layer comprises about 50 to about 95% by weight of a crystalline polyamide and about 50 to about 5% by weight of an amorphous polyamide and that the multi-layer film is produced by stretching a flat film at least in the lateral direction; and a process for preparing the multi-layer film.

Abstract: Laminates containing a layer of conductive polyaniline are provided for various uses such as actuator devices. The laminates are controllably deformable and can operate on an electromechanical, chemomechanical, and mechanoelectrical modes. The laminates are preferably constructed so as to have a first flexible layer of polyaniline and a second flexible layer of polyaniline surmounted thereon. The polyaniline layers are separated by an electronically insulating layer.

Abstract: A film combination has a pair of polymeric substrate films. At least one surface of each has a surface free energy of at least 35 dynes/cm and a primer coating on each. Each primer coating has a layer of poly(vinylalcohol) containing a cross-linking means. Each film of the pair is positioned with the poly(vinylalcohol) layers in intimate contacting relationship before any substantial cross-linking occurs.

Abstract: A plastic sheet, preferably of plasticized partial polyvinyl butyral, for a laminated safety glazing, having means dispersed on its surface, preferably comprising a multiplicity of spaced projections, capable of resisting adhesion to a rigid panel, such as glass, of such a glazing when the sheet is laminated to the panel, the area of the sheet surface without such dispersed means having high affinity for adhesion. The projections physically block adhesion of a dispersed area of the sheet to the panel in that the means on the sheet surface have no or weak interfacial adhesion. The multiplicity of space projections also have low or no affinity for adhesion when in blocking contact with each other or with another plasticized partial polyvinyl butyral surface and thereby increase blocking resistance.

Abstract: Disclosed is a process for producing a titanium dioxide pigment used for a resin-coated paper type photographic support, comprising the following steps:(a) a step of adding at least one alkaline earth metal compound in an amount of 0.01-2.0% by weight in terms of a metal oxide based on the titanium dioxide before calcination step and(b) an acid-washing step of washing the titanium dioxide at acidic state after the calcination step and before a step of surface treatment with a hydrated metal oxide,and wherein particle size of the titanium dioxide pigment is 0.110-0.150 .mu.m shown by number-average diameter obtained by measuring the diameter in a certain direction using an electron microscope. A photographic support which comprises the above titanium dioxide pigment is also disclosed. Occurrence of die lip stain and microgrit are substantially reduced in the photographic support and a photographic material made thereof exhibits improved image sharpness.

Abstract: A highly glossy thick aesthetic laminate surface layer is achieved by using pre-cured particulates of the impregnating resin preferably along with an initial binder material and abrasion resistant mineral particles. The protective overcoating may be applied in a thick layer to give gouge resistance and a deep look in the glossy laminate. The overcoated decor sheet is pressed against a mirror plate in the laminate manufacturing process, and gives a gloss meter reading well over 100. Because the impregnating resin and the pre-cured particulates have the same index of refraction, the transparency of the coating and the resultant clarity of the underlying decor sheet are excellent.

Abstract: The coating for a prothesis system has a resorbability gradient in the direction perpendicular to the surface of the prothesis system, the internal layer being the least resorbable. It can consist of phospho-calcium material or of two or several successive layers having different resorbabilities and having said resorbability gradient. The prothesis systems covered with the coating according to the invention are used in surgery for the provision of thigh-bone protheses as well as protheses for the facial, ear, nose and throat surgery and the like.

Abstract: Improved bonded properties of dry-laminated flexible film substrates, for instance laminates comprising films of thermoplastics such as polyolefins, polyesters, and polyamides, as well as paper, cellophane, and metals, particularly after exposure to boiling water, are obtained with polyurethane dispersion adhesives when a plural aziridine or carbodiimide compound, or a mixture of a plural epoxy compound with a plural aziridine or carbodiimide compound, is employed as the crosslinker for the adhesive system.
