Abstract

Rosin - urea - formaldehyde - water dispersions suitable for impregnating paper in pulp or sheet form are obtained by combining a urea-formaldehyde intermediate condensate having a water tolerance of 0-30 per cent at 20 DEG C. with rosin itself or with an alkaline solution of rosin or with a rosin soap, e.g. sodium rosinate and dispersing the mixture in water. Casein may also be present as described in Specification 582,235, and the urea-formaldehyde condensate is prepared as described in that Specification. The rosin may be mixed with the condensate (a) in solution in aqueous sodium hydroxide, (b) as a 4 per cent alkaline solution of sodium rosinate, (c) by mixing 1 part dry sodium rosinate with 100 parts condensate. Hydrogenated rosins may be used.
