摘要:
A thermosetting resin is prepared by mixing or reacting (a) an alkylene diamine or polyalkylenepolyamine with (b) an epihalohydrin (preferabiy chiorohydrin), and (Y) a watersoluble resin obtained by reacting (i) urea, (ii) a polyalkylenepolyamine, and (iii) a dibasic carboxylic acid (e.g. adipic) and reacting the resultant polyamidopolyurea (PAPU) formaldehyde. The PAPU can be made by reacting (i) + (ii) and the product with (iii), or (ii) + (iii) and the product with (i), at specified reaction conditions. (Y), (a) and (b) may all be reacted or mixed together, or first (Y) and (b) and then (a), or (a) and (b) then (Y). The thermosetting resin is mixed into a paper coating composition including a conventional pigment, binder and water, and the composition is coated onto paper and dried to make a coated paper which has good waterresistance (due to the resin (Y)) whilst being receptive to rotary offset printing ink. ,
摘要:
Fabrics, particularly cellulosic fabrics is resin finished with a combination of 1,3-dimethylglyoxalmonourein and trimethylolpropane, whereby the fabrics has improved crease resistance and shrink-proofing and generates no unpleasant odor.
