Abstract

The purpose of the present invention is to provide: a polyester resin for antifouling coating materials, which enables an antifouling coating material to be in a one-pack form by improving storage stability, while maintaining low VOC level, and which is capable of improving curability, while providing long-lasting good antifouling properties and good coating film properties; a method for producing the polyester resin for antifouling coating materials; and an antifouling coating material composition. A polyester resin for antifouling coating materials is obtained by reacting (a) a tri- or higher hydric alcohol, (b) a dibasic acid or an anhydride thereof and (c) a dihydric alcohol, and then reacting the resulting product with (d) an alicyclic dibasic acid or an anhydride thereof.

Abstract

Disclosed is a urethane (meth)acrylate composition which is obtained by reacting a polyester polyol obtained from a polyvalent carboxylic acid and a polyhydric alcohol, a polyisocyanate and a (meth)acrylate having an active hydrogen. The urethane (meth)acrylate composition is characterized in that a part of the polyhydric alcohol is composed of a diol having one side chain on a straight chain having 3-7 carbon atoms, and the polyisocyanate contains at least one member selected from hexamethylene diisocyanate, diphenylmethane diisocyanate, hydrogenated diphenylmethane diisocyanate and tetramethylene diisocyanate.

Abstract

A process for the production of shoes which comprises the step of melting a reactive hot-melt adhesive mentioned below under heating and applying the melt to the adhesive surface of at least one adherend, the ultraviolet treatment step of irradiating the adhesive with an ultraviolet light in a dose exceeding 100mJ/cm2 and below 1,200mJ/cm2 to polymerize the polyurethane prepolymer contained in the adhesive, and the bonding step of placing the other adherend on the resulting adhesive to bond both adherends to each other. The reactive hot-melt adhesive is one which comprises both a polyurethane prepolymer containing a noncrystalline polyol and bearing a (meth)acryloyl group and an isocyanate group at the ends and a photopolymerization initiator and exhibits a viscosity of 300Pa쮏s or below at 80°C. The process brings about simplification in the stage of work and reduction in the working time and enables the production of shoes excellent in durability.

Abstract

Disclosed is a method for producing a shoe, which comprises the following steps: a pretreatment step for melting a reactive hotmelt adhesive agent as mentioned below by heating and providing the molten adhesive agent onto the bonding surface of at least one of objects to be adhered to each other; an ultraviolet ray treatment step for irradiating the adhesive agent with an ultraviolet ray having an intensity of 100 to 1,200 mJ/cm2 exclusive to cause the polymerization of a polyurethane prepolymer contained in the adhesive agent; and a bonding step for superimposing the bonding surface of the other object on the adhesive agent provided on the at least one of the objects to adhere the both objects to each other. The reactive hotmelt adhesive agent comprises: the polyurethane prepolymer which has a (meth)acryloyl group and an isocyanate group at the end terminus of the molecule and contains a non-crystalline polyol and a crystalline polyol, wherein the non-crystalline polyol is contained in an amount of 20 to 90 mass% relative to the total amount of the polyols; and a photopolymerization initiator. The adhesive agent has a viscosity of 300 Pa s or less at 80˚C. In the method for producing a shoe, the process of operation can be simplified and the time of operation canbe shortened. The method enables to produce a shoe having excellent durability.
