A composition for a pressure-sensitive adhesive, includes (A) a (meth)acrylic ester polymer having a trithiocarbonate structure, having hydroxyl groups at both ends of a molecule and having a weight-average molecular weight (Mw), as measured by gel permeation chromatography, of 50,000 to 300,000, and (B) an isocyanate compound having an average number of isocyanate groups in one molecule being more than 2.
摘要:
There is provided a polyester-based primer composition including 100 parts by weight of a polyester resin, 1 to 20 parts by weight of water-dispersible particles, and water as a remainder. Since a polyester-based primer composition of the present disclosure is excellent in water resistance and solvent resistance differently from a urethane primer composition, the polyester-based primer composition may obtain sufficient adhesive strength between a protection film and a functional coating layer even without assistance from additives such as a cross-linking agent, and may retain stable adhesive strength for a long period of time.

摘要:
To prepare a polyester polyol in which a lactone is ring-opening addition polymerized with the compound represented by formula (I). (wherein each of A1 and A2 represents an alkylene group having not less than 2 carbon atoms, A3 represents an alkylene group, X represents a cationic component, and each of n and m represents an integer of not less than 1.)The polyester polyol has a high hydrophilic group and high solubility in a solvent (particularly, a low-boiling organic solvent used in the production of a polyurethane) and can design an aqueous polyurethane desirably and produce the aqueous polyurethane.
摘要:
A polyurethane dispersion is prepared by reacting a hydroxy-functional sulfonated unsaturated alkyd with an isocyanate in the presence of one or more vinyl monomers to form a blend containing the vinyl monomers and a sulfonated polyurethane polymer containing ethylenic groups. The blend is dispersed in water and the vinyl monomers are reacted by free radical polymerization.
摘要:
Disclosed is a polythiourethane having a high refractive index and low dispersion which is obtained through a reaction between a polythiol component containing one or more polythiocarbonate polythiol (preferably one having a —(CO—S—R—S)— structure (wherein R represents a divalent hydrocarbon group) and a number average molecular weight of 200-2,500) and a polyisocyanate component containing a polyisocyanate and/or a polyisothiocyanate. This polythiourethane is useful for plastic lenses, prisms, optical fibers, substrates for information recording, colored filters, infrared absorbing filters and the like.
摘要:
An aqueous urethane resin dispersion for bonding can be used in wet lamination and dry lamination and can be reactivated easily at a low temperature of about 50 to 70° C. after drying, and is also superior in coatability, adhesive strength, and heat resistance. The aqueous dispersion of a polyurethane resin is superior in contact adhesiveness immediately after lamination and also has good permeability and good coatability not only on bases having smooth surfaces such as plastics and metals, but also on porous bases such as fibers, papers, and buffed leathers; an aqueous adhesive using the aqueous dispersion; and an article to which it is applied. The aqueous polyurethane resin dispersion has at least one of a sulfonate group and a carboxylate group, wherein an average particle diameter of the polyurethane resin is 0.05 to 0.30 μm and a surface tension of the aqueous dispersion (A) is 40 mN/m or less.
