摘要:
Erasable paintings used to paint a design on the at least one paintable surface of the footwear. The erasable paintings are insoluble in water and thus can withstand any weather conditions. The present invention also provides an erasing solution for completely erasing the erasable from the paintable surface. The present invention also provides an article of footwear having at least one paintable surface and at least one erasable painting. The article of footwear may also include an erasing solvent to erase the at least one erasable painting. The article of footwear may also include a spray and/or liquid to make the painting permanent and/or a painting instrument. The article of footwear may also include various accessories.

摘要:
A polymer polyol (I) is provided that is formed of a polyol (A), polymer particles (B) obtained by polymerization of an ethylenically unsaturated compound (b), and an active-hydrogen-containing compound (d) having an aromatic ring and having a number-average molecular weight of 150 to 2,000, wherein a content of (d) is 1 to 20% on the basis of a weight of (B). The polymer polyol of the present invention contains polymer particles having sufficiently small particle diameters, has a low viscosity, and has excellent handleability. A polyurethane resin obtained by using the polymer polyol of the present invention has excellent mechanical strengths such as elongation at break.
摘要:
An aqueous resin composition with gas barrier properties contains (i) polyurethane resin having aurethane group and a urea group in a total concentration of 25 to 60% by weight and having a acid value of 5 to 100 mgKOH/g, (ii) a swelling inorganic layered compound (e.g., a water-swelling mica, and a montmorillonite), and (iii) a polyamine compound having an amine value of 100 to 1900 mgKOH/g. The polyurethane resin (i) is obtained by a reaction of (A) an aromatic, araliphatic or alicyclic polyisocyanate, (B) a polyhydroxyalkanecarboxylic acid, and at least one component selected from (C) a C2-8alkylene glycol and (D) a chain-extension agent (e.g., diamine, hydrazine and a hydrazine derivative), and neutralized with a neutralizing agent. The proportion of the acid group of the polyurethane resin (i) relative to the basic nitrogen atom of the polyamine compound (iii) is 10/1 to 1/5 as the equivalent ratio. A laminated film with high gas barrier properties is obtainable by coating a base film with the aqueous resin composition. The present invention provides an aqueous resin composition with excellent gas barrier properties, and a laminated film using the same.
