摘要:
A polyurethane composition comprising a polyurethane and at least one dye selected from the group consisting of metal complex dyes, vat dyes, sulfur dyes and acid dyes. The polyurethane is synthesized by the reaction of a polymeric diol containing a polyoxyethylene chain as a minor proportion, an alicyclic diisocyanate, an alicyclic diamine and hydrazine in particular proportions. This polyurethane composition is little susceptible to deterioration by light and is suitable for use as a component of artificial leather or as a coating material for fabrics.
摘要:
Polyurethane compositions comprising a polyurethane synthesized by reacting a diol, a specific alicyclic diisocyanate, a specific alicyclic diamine and hydrazine or isophthalic acid dihydrazide in specific proportions and a solvent therefor have good solution stability and, when applied as coating compositions, give coats with good light stability, good surface properties, high softening points and sufficient flexibility at low temperatures.
摘要:
An aluminum atom- and monocarboxylic acid residue-containing polyester is provided. Using the polyester as an adhesive or a base, laminates and laminated hollow vessels which comprise, as the constituent elements, the polyester and an ethylene-vinyl alcohol copolymer can be produced. The laminates and laminated hollow vessels are suitable for use as packaging materials or containers for food and drink.

摘要:
The tube of the present invention has no or very small local minute nonuniformity in thickness of EVOH layer, and therefore drawn-formed articles such as blow bottle obtained by draw molding the tube have no streaks and are superior in appearance.
