摘要:
A pigment that exhibits excellent image density, dispersibility, storage stability, and resolubility, and forms an ink film that exhibits marker resistance and rubfastness is provided. A polyurethane resin-bonded pigment is produced by bringing (I) a pigment having a surface acidic group into contact with (II) a water-dispersible polyurethane resin having a tertiary amino group and an anionic polar group or a nonionic polar chain in an aqueous medium. The pigment (I) is preferably self-dispersible carbon black having a surface acidic group.
摘要:
A tin-containing polyurethane resin having a melting temperature of 40 to 180° C., measured by DSC at a heating rate of 10 K/min and prepared by carrying out a condensation reaction between a diorganotin compound and carboxyl groups of a carboxyl-functional polyurethane resin, wherein the molar ratio between the tin and the carboxyl groups is 1:2-20; and liquid coating compositions containing solid particles of the tin-containing polyurethane resin.
摘要:
An aqueous ink jet ink is made by forming a mixture of a pigment, an optional dispersant if the pigment is not self-dispersing, and a urethane polymer or prepolymer dispersion in water. This ink is useful in a variety of ink jet printing applications such as printing on wide format substrates and textiles.
摘要:
An aqueous dispersion comprising a mixture of a first dispersion and a second dispersion, said first dispersion comprising at least one (meth)acrylated pre-polymer (A), and said second dispersion comprising at least one thiol-functional compound (B), said aqueous dispersion optionally comprising at least one ethylenically unsaturated compound (C).
摘要:
The present invention relates to radiation-curable, aqueous dispersions based on polyurethane acrylates (i), which are characterized in that the polyurethane acrylate (i) comprises, as formation components, A) one or more aromatic polyepoxy(meth)acrylates having an OH number of 20 to 300 mg KOH/g of substance, C) one or more oligo- or polyesters containing unsaturated fatty acids having an OH number of 15 to 300 mg KOH/g of substance and an iodine number of greater than 50 g of I 2 /100 g of substance, E) one or more compounds having at least one group reactive toward isocyanate and additionally at least one hydrophilizing group, and F) one or more organic polyisocyanates, to a process for production thereof, to the use of the coating compositions as coating materials and/or adhesives, and to articles and substrates provided with these coating materials and/or adhesives.
摘要:
The present invention relates to a hydrophobically modified alkylene oxide urethane polymer comprising structural units of a polyalkylene glycol, an alkoxylated polyol having 50 to 250 repeating alkylene oxide units, an aliphatic diisocyanate, and a capping agent, and a process for preparing the polymer. The composition of the present invention is useful as a rheology modifier for coating compositions.
