摘要:
A stainproofing polymer having: (i) a reactive group selected from the group consisting of a carboxyl group or its salt, a hydroxyl group, an epoxy group, a phosphoric acid group, an alkoxysilane group, an imine group, a sulfonic acid group, an amino group, an isocyanate group and a blocked isocyanate group; and (ii) a fluoroalkyl group, characterized in that a melting point of a monomer having a fluoroalkyl group, which constitutes the polymer, is at least 70° C. and a melting point of the stainproofing polymer is at least 50° C., gives durability capable of maintaining sufficient water- and oil-repellency after cleaning.
摘要:
The present invention provides a copolymer whose durability on cleaning is improved while maintaining good water- and oil-repellency. Disclosed is a copolymer having: (i) a fluoroalkyl group, (ii) a urethane or urea linkage, and (iii) a functional group selected from the group consisting of a carboxyl group, a carboxylic anhydride group, an epoxy group, a phosphoric group, an alkoxysilane group, a imine group, a sulfonic group, an amino group, an isocyanate group and a chlorine atom, and a stainproof agent containing the copolymer as an active component.
摘要:
A textile having durability of maintaining water- and sufficient oil-repellency and soil releasability before and after cleaning can be obtained by a method of preparing a treated textile, having steps of: (1) preparing a treatment liquid containing a water- and oil-repellent agent, (2) adjusting pH of the treatment liquid to at most 7, preferably at most 3, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile, wherein the water- and oil-repellent agent is an emulsion containing a fluorine-containing compound and an emulsifier, the fluorine-containing compound is a fluorine-containing polymer and/or a fluorine-containing low molecular weight compound, and the emulsifier contains an anionic surface active agent having pKa of at least 2.

摘要:
An antiglare-treated article comprising an acrylic resin substrate and a fluorine-containing polymer coating formed on the surface of the substrate, wherein the thickness of the coating is in the range between 0.03 and 0.5 &mgr;m, and the fluorine-containing polymer has a refractive index in the range between 1.30 and 1.40 and comprises a block which is compatible with the acrylic resin and a block comprising a fluorine-containing elastomer. This treated article can be stably produced at low costs although it has the same abrasion resistance and antiglare effects as those of conventional antiglare-treated articles, or it has better antiglare effects than conventional antiglare films while maintaining abrasion resistance.
