Provided is a cladding composition which contains metal powder, a binder, and an organic solvent in a case of bonding a metal base material and a resin member to each other. Further, provided is a method for producing a metal/resin bonded member, including a step of coating at least a portion of a metal base material with the cladding composition; a step of irradiating the coated portion of the metal base material which has been coated with the cladding composition, with a laser; a step of disposing the resin member on the laser irradiation portion of the metal base material; and a step of heating an interface between the laser irradiation portion and the resin member so that the metal base material and the resin member are bonded to each other.

An intermediate base material has high handleability and shape conformity to complicated shapes and serves to perform high-yield production, even by low pressure molding, of fiber reinforced plastic material that do not suffer from significant generation of molding defects, such as creases and voids, that can cause a decrease in strength and that has good mechanical characteristics, decreased variations therein, and high dimensional stability. The prepreg includes a layer containing reinforcement fibers impregnated with a resin composition and the impregnation rate with the resin composition in the prepreg is in a predetermined range. It is characterized by being an incised prepreg having a plurality of incisions, being at least partly formed of reinforcement fibers with a predetermined fiber length, and having a reinforcement fiber content by volume Vf in a predetermined range.

Described herein is a laminate including at least one first layer of at least one first metal and at least one further layer of a polymer composition (PC). Also described herein is a process for producing the laminate.

A packaging bag for packaging a polyvinyl alcohol-based resin that contains a modified group having active hydrogen, the packaging bag including a film having a water vapor permeability of 10 g/m.sup.2/day or less. Accordingly, when a polyvinyl alcohol-based resin that contains a modified group having active hydrogen is packaged with the packaging bag, the storage stability of the polyvinyl alcohol-based resin that contains a modified group having active hydrogen can be improved, and hence an aqueous solution of the polyvinyl alcohol-based resin that contains a modified group having active hydrogen, the solution being reduced in insoluble matter content, can be obtained even after long-term storage thereof.

The present invention relates to a process for laminating components with sheets, in which an adhesive is applied to the surface of the laminating sheet and/or of the component in a grid-like manner, so that, after the sheet and the component are joined, the adhesive is arranged between the sheet and the component, and the regions between the applied adhesive form a channel system that enables the removal of the air that is present between the component and the sheet. The invention further relates to a laminated molded part obtainable by the above-outlined process. The use of an adhesive grid provided between a component and a laminating sheet results in a reduction or prevention of air inclusions when the component is laminated with a laminating sheet.

A soil reinforcement membrane that promotes grass, plant, and vegetation growth in a variety of temperatures and geographic locations and increases water retention. The soil reinforcement membrane is flexible enough to be placed on a variety of landscapes and promotes growth in a variety of soils. The soil reinforcement membrane consists of an upper layer and a lower layer with a cultivating compound dispersed uniformly between the two layers.
