Abstract: The present invention provides ink and coating compositions for printing on non-woven substrates or fabrics. Advantageously, the compositions of the invention can be used either as one component (1K) or two component (2K) ink systems. The compositions of the invention exhibit improved properties, such as ink adhesion ratings, as shown by a rub test, compared to commercially available inks designed to be printed on non-woven substrates.

Abstract: An aqueous polyurethane resin dispersion, the polyurethane resin is obtainable by reacting an allophanate based isocyanate according to general formula I or II, optionally a polyether diol, a polyol containing a quaternary N-atom or tertiary amino group and a polyol selected from the group consisting of polyester polyol, polyether polyol, polycarbonate polyol, a polyacrylate polyol, a polyolefin and a polyamide polyol. The polyurethane resin is suitable as a resin in treatment liquids of substrates and images made by inkjet printing.

Abstract: 一种涤纶定岛超纤用聚氨酯树脂及其制备方法，按质量百分含量计，该聚氨酯树脂的原料配方包括二异氰酸酯5～10％、多元醇化合物15～25％、小分子二元胺扩链剂1～2％、小分子二元醇扩链剂0.2～0.5％、催化剂0.001～0.005％、溶剂65～75％、抗氧剂0.02～0.1％和终止剂0.02～0.1％，其中，多元醇化合物为聚醚二元醇和聚酯二元醇按质量比为2～4:1的混合物；聚酯二元醇为含酰胺基的己二酸系二元醇。在聚氨酯合成过程中采用分步过量预聚法工艺，提高小分子醇类、胺类扩链剂在分子链中分散均匀性，降低聚氨酯树脂软硬段相分离程度，可提高聚氨酯树脂对分散染料的结合力，提高涤纶定岛超纤的染色牢度。
