Abstract: A semisynthetic paper with low bulk comprises a continuous, chemically bonded, open fibre network formed by cellulosic vegetable fibres and fragments of urea-formaldehyde condensate, the fragments being precured before paper web formation and being cured a second time when drying the paper web.A method of producing a semisynthetic paper with low bulk comprises the steps of forming precured fragments of a urea-formaldehyde condensate, forming a stock of the fragments and cellulosic vegetable fibres, including in the stock a water-insoluble latent curing agent, forming a paper web from the stock, and drying the paper web, the fragments being cured a second time during the drying operation.
