Abstract: A paper transporting felt includes a base layer, a first batt layer formed on a wet paper side surface of the base layer, a second batt layer formed on a roll side surface or a shoe side surface of the base layer, and a wet paper contacting fibrous layer formed on a wet paper side surface of the first batt layer so as to come into direct contact with a wet paper. The wet paper contacting fibrous layer is made of modified cross-section fibers.

Abstract: A water-based metal surface treatment agent for the surface treatment of metals including aluminum products such as pre-coated aluminum sheets gives excellent coating film adhesion, flexibility and acid resistance. The water-based metal surface treatment agent contains the following components (1) to (3): (1) A copolymer, containing in a side chain, a diketene or ketoester capable of switching between keto and enol tautomeric forms, and containing at least one hydrophilic side chain containing a cationic group, an anionic group, or a nonionic group; (2) An epoxy resin modified with a phosphoric acid type compound; and (3) A water-soluble curing agent.

Abstract: The present invention provides an organic carboxylate composition that has long working life, cures epoxy resins, and improves adhesive properties, and also provides a method for producing the same. An organic carboxylate composition, obtained by heating and mixing a basic silane coupling agent and an amine compound with a softening point or melting point of 40° C. or greater together with an organic carboxylic acid; a method for producing the same; an additive for epoxy resin that contains this as the active ingredient thereof; and an epoxy resin composition containing the same. The basic silane coupling agent should preferably be a specific imidazole-group containing silane coupling agent, amino group-containing silane coupling agent, dialkylamino group-containing silane coupling agent, monomethylamino group-containing silane coupling agent, benzimidazole group-containing silane coupling agent, benzotriazole group-containing silane coupling agent, and pyridine ring-containing silane coupling agent.

Abstract: Papermaking felt containing a hydrophilic urethane resin that can maintain functions such as water drainage, wet-paper smoothness, and wet-paper transportability by imparting a hydrophilic property to the papermaking felt thereby preventing the deposition and accumulation of adhesive contaminants without impairing the compression recoverability of the felt thus sustaining its antifouling capability.
